[GTK] Layout Tests are failing since the change of the computed value of line-height:normal

• Component: CSS
• Status: NEW ---

[Marcos Chavarría Teijeiro (irc: chavaone)]

The fast/css/font-shorthand-from-longhands.html layout test is failing since r179168 (http://trac.webkit.org/r179168).

The test replaces "normal" value by a numeric value. GTK+ port results have different numeric values.

The diff can be found here https://build.webkit.org/results/GTK%20Linux%2064-bit%20Release%20%28Tests%29/r179867%20%286096%29/fast/css/font-shorthand-from-longhands-pretty-diff.html

[Marcos Chavarría Teijeiro (irc: chavaone)]

More tests are failing due to the same revision the error is the different numeric values from the expected and the test result.

[Sylvain Galineau]

To be clear, r179168 only made line-height: normal compute to a length instead of 'normal'. What we see here are line-height length values changing, most of them by 1px. It seems we may have stumbled into a difference between ports that wasn't visible before.

I will try to look into this though I'm not able to build on Linux at this time.

[Lorenzo Tilve]

editing/pasteboard/simplfiying-markup-should-not-strip-content.html layout test was being skipped.

Passing again after <http://trac.webkit.org/changeset/186191>. Unskipped in <http://trac.webkit.org/changeset/194218>.

[Carlos Alberto Lopez Perez]

r200534 <http://trac.webkit.org/r200534> removed the test fast/css/line-height-text-autosizing.html and made it iOS specific fast/text-autosizing/ios/autosize-width-expected.html
