Subject: 29.3; Tab-bar-mode tabs visually truncated when modifying
 internal-border-width on PGTK

(tab-bar-mode)
(modify-all-frames-parameters '((internal-border-width . 10)))

When evaluating the above code using 'emacs -Q' built with PGTK, the
tabs appear vertically truncated depending on the chosen internal
border width value.
This behavior can be observed even with low values such as 1 or 2,
although it may be difficult to notice. The effect becomes more obvious
starting at 4 or 5. When the values reach 24 or higher, the tabs become
completely hidden. This may be related to the font size.
Hovering the mouse over the tab-bar displays the caracter/element under
the cursor correctly, but everything else remains hidden or truncated.
