Description Amanda Falke 2023-05-09 08:23:20 PDT

Other browsers never render any visible tab glyphs, even if the font has a visible glyph for the tab character.

We need to ensure that complex text path does not render visible tab glyphs. (Our patch in 249360@main implemented this for simple text path; we need to do this also for complex text path.) 

This fix will also fix the fast/text/nbsp-no-space.html LayoutTest for WPE/GTK (glib).
