Thank you for the report. Could you try this fix and see if it resolves the issue?

9774651 used \a which indeed matches [A-Za-z] in Vim's regex, not BEL. The fix changes it to \x07 (inside []) and %x07 (outside []).

-  exe 'silent! keepj keepp %s/\v\e\]8;[^\a\e]*%(\a|\e\\)//e' .. (&gdefault ? '' : 'g')
+  exe 'silent! keepj keepp %s/\v\e\]8;[^\x07\e]*%(%x07|\e\\)//e' .. (&gdefault ? '' : 'g')

I confirmed the fix resolves this issue and tested the pattern with the shell script below.

#!/bin/bash
