REGRESSION(r177637) [HarfBuzz] [GTK] Missing glyph symbol is not rendered properly.

• Component: Layout and Rendering
• Status: RESOLVED FIXED

[Carlos Alberto Lopez Perez]

After r177637 <https://trac.webkit.org/r177637> and r177876 <https://trac.webkit.org/r177637> the missing glyph symbols are not rendered.

On bug 139905 a crash caused by r177637 was fixed on r178115 <http://trac.webkit.org/r178115> but that was an incomplete fix, because looking at the results of the tests the missing glyph symbol (the square) is now gone. http://people.igalia.com/clopez/bug-139905-results-img/results.html

On the GTK port, at least the following tests are affected:

Regressions: Unexpected text-only failures (15)
  fast/css/line-height-determined-by-primary-font.html [ Failure ]
  fast/ruby/bopomofo-letter-spacing.html [ Failure ]

I have updated the GTK test expectations on r178121 <https://trac.webkit.org/r178121>

[Diego Pino]

These tests are passing after updating baselines in 276098@main.

https://results.webkit.org/?suite=layout-tests&test=fast%2Fcss%2Fline-height-determined-by-primary-font.html&platform=GTK

After updating test expectations in 279290@main, there are no more tests referring to this bug. Closing bug.
