bug#52881: setting tab-line-separator to any value breaks clicking tabs with mouse

[Ben Sferrazza]

This is using Emacs 27.2 on a CentOS8 machine at work. I use Emacs exclusively with -nw in a terminal with mouse support enabled.

 

Using something like

 

(setq tab-line-separator “ | “)

 

breaks the ability to click on a tab to select it. Leaving it at the default value avoids the bug.

 

Thanks,

Ben
