[master-8d0c8076] xwidget-browser-url crash on Linux Xwayland KDE

[Eval EXEC <execvy@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 33919 bytes --]

Hello,

I build emacs from master-8d0c8076c3f2c27bd8ff0dbc72d046c64e1dde44 by:

```bash

#!/usr/bin/env bash
set -ex

make extraclean

BRANCH_NAME=$(git branch --show-current | sed 's/\//_/g')
COMMIT_ID=$(git rev-parse HEAD)
BUILD_DIR=${BRANCH_NAME}-commit-${COMMIT_ID}-03
INSTALL_PREFIX=$(realpath ../emacs-build/${BUILD_DIR})

./autogen.sh
./configure CFLAGS='-O0 -g3 -ggdb -mtune=native -march=native'\
   --prefix=${INSTALL_PREFIX} \
   --with-imagemagick  \
   --with-modules \
   --with-cairo --with-cairo-xcb \
   --without-compress-install \
   --with-native-compilation  --with-mailutils\
   --enable-link-time-optimization \
   --with-tree-sitter --with-xinput2  --with-xwidgets \
   --with-dbus  --with-native-compilation=aot \
   --with-file-notification=inotify\
   && make -j30 install

```

And I launch it by emacs -Q:

```bash

❯ ~/.local/bin/emacs -Q

(emacs:2083090): GLib-GIO-CRITICAL **: 20:07:01.416:

This is a bug!  Please report this to bug-gnu-emacs@gnu.org!

When compiled with GTK, Emacs cannot recover from X disconnects.
This is a GTK bug: https://gitlab.gnome.org/GNOME/gtk/issues/221
For details, see etc/PROBLEMS.
[1]    2083090 abort (core dumped)  ~/.local/bin/emacs -Q

```

And it crashed. the core dump backtrace is:
