1. emacs -q -l test.el
2. Create a new buffer in mhtml-mode
3. Add the following two lines:

   %%var1%%
   "%%var2%%"

4. Inspect the syntax of the % char (C-u C-x =) on both lines

% in double quotes has word syntax which seems unexpected.

If we do something similar in Emacs 26 both % chars have punctuation
syntax.

I can't seem to be able to reproduce your scenario in Emacs 28 (in fact, 
I get %var1 and %var2 highlighted as variables), but it might be related 
to the

   "\\([\"']\\)[^\"'<>]*"

rule in sgml-syntax-propertize-rules.

If you could double-check the expected and actual behaviors in the 
current master, though, that would be great.

Yes I can confirm it's this rule that seems to remove syntax-table
property that has been applied by preceding rules.

I can reproduce this bug by simplifying the said rule to

  ("\\([\"']\\)[^\"'<>]*" (1 "."))

Unfortunately I don't have emacs 28 at hand so cannot test immediately.

I'm unable to reproduce this -- all the % signs have

  general-category: Po (Punctuation, Other)

syntax, as far as I can tell (both in Emacs 27.1 and 29).  So I seem to
be unable to reproduce this problem.  Are you still seeing this in
recent Emacs versions, and if so, do you have a complete recipe to
reproduce it?

I tested the bug again in emacs 28.1 nothing seems to have changed 

               syntax: w 	which means: word

Do you have a complete recipe, starting from "emacs -Q", to reproduce
this?

That's what I did following step by step in the bug report. However I
noticed you were posting from the subheading "Character code properties"
in the output of C-u C-x =. I was taking the output from the top under
key "syntax:". Is this causing the confusion?

Leo

Oh, you mean this?

               syntax: w 	which means: word

Yes, I can reproduce that.
