            Bug ID: 256524
           Summary: [GTK][WPE] complex text path should not render visible
                    tab glyphs
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Text
          Assignee: webkit-unassigned at lists.webkit.org

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 at 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).
