When in a terminal with the tab-line showing and mouse enabled, the
following error in shown when dragging the mode line down:

<tab-line> <mouse-movement> is undefined

I believe the following diff fully fixes the issue:

Thanks, but I cannot reproduce this, at least not on MS-Windows (I
don't have access to a Posix system with a mouse-capable text
terminal).

Does it matter which part of the mode line you drag?

I can reproduce this in xterm in master branch commit
2fca889cfb4fa495a6ffa0c7fe368551ee9a32bc.

It doesn't seem to matter.  I pulled from the final '----' part and
could reproduce the message.

Thanks.

And the fix solves the problem?

Does anyone have a Linux terminal with GPM mouse and can test there?

I can also reproduce the problem on GNU/Linux with emacs-29 and master,
and the fix works for me.

> Does anyone have a Linux terminal with GPM mouse and can test there?

I do and after splitting the window and enabling gpm-mouse-mode I can't
drag the mode line with GPM mouse at all, whether global-tab-line is
enabled or not (on emacs-29 and master), and there are no errors or
other notifications in *Messages*.  Is dragging the mode line
supposed to work in the Linux terminal with GPM mouse?

I also have a GPM mouse available and I see different behavior.

On Emacs 28.2 (installed from Debian package): Dragging the mode line 
works fine, even if the tab line is visible. (GPM mouse mode is enabled 
by default)

On HEAD (2407f8): Dragging the mode line does not work until I disable 
and re-enable GPM mouse mode. Then it works fine.

This indicates two things to me:

1. My original patch is likely inaccurate.  A better fix would be to 
align the mouse-movement event with how it is emitted under GPM and DOS. 
  I will investigate.

2. Something broke with how GPM mouse mode is enabled between Emacs 28.2 
and HEAD.  I can help with a bisect here.

I can now confirm this (and see the same on the emacs-29 branch as on
master; I can't currently test emacs-28).  My previous report was
erroneous: I had never used (or even heard of) gpm-mouse-mode before
reading this bug thread, and didn't realize it was enabled by default,
so all I had done was to disable it; on re-enabling it, dragging works
as Jared reported, both without and with the tab line.

As noted, I see the same behavior on master and emacs-29, so it may be
quicker to use the latter for bisecting (I cannot help with that for the
time being, sorry).

Thanks, please do, on both counts.

Following up on #2:  The issue here is that after a28ede, 
gpm-mouse-tty-setup is never added to tty-setup-hook since it is only 
added within gpm-mouse-mode. This is clearly visible by checking the 
value of tty-setup-hook at startup, and after toggling gpm-mouse-mode 
off and on again.

The following simple patch fixes that, while leaving the details of how 
gpm-mouse-mode works an internal detail:

--- a/lisp/term/linux.el
+++ b/lisp/term/linux.el
@@ -13,6 +13,9 @@ terminal-init-linux
   ;; Compositions confuse cursor movement.
   (setq-default auto-composition-mode "linux")

+ ;; Ensure additional terminal setup is done when `gpm-mouse-mode' is 
enabled.
+ (ignore-errors (when gpm-mouse-mode (gpm-mouse-mode 1)))
+
   ;; Don't translate ESC TAB to backtab as directed by ncurses-6.3.
   (define-key input-decode-map "\e\t" nil)

One could also just revert just the linux.el changes in a28ede, though 
that assumes that gpm-mouse-enable exists.

Leaving this as one email so both changes are easy to follow.  I believe 
both patches are valuable to apply.

And I have a better patch here.  The real issue is that xt-mouse 
generated mouse-movement events were getting prefixed with mode-line or 
tab-line symbols but other mouse-movement events were not.  The 
following simple change fixes that:

--- a/lisp/xt-mouse.el
+++ b/lisp/xt-mouse.el
@@ -63,9 +63,14 @@ xterm-mouse-translate-1
            (is-move (eq 'mouse-movement ev-command))
            (is-down (string-match "down-" (symbol-name ev-command))))

-      ;; Mouse events symbols must have an 'event-kind property with

Thanks, I've now installed both patches on the emacs-29 branch, and
I'm closing this bug.
