branch: emacs-28
commit 47e09d1855488a9fa4608ef6c6da64dff58fc871
Author: Juri Linkov <juri@linkov.net>

    Copy parent face attributes to tab-line-tab-current instead of inheriting 
face
    
    * lisp/tab-line.el (tab-line-tab-current): Don't inherit face from
    'tab-line-tab' to not inherit the face attribute :height from 'tab-line',
    because :height of mouse-face is added to the base face.
    Copy here most of the parent face attributes (bug#50798).
