How the tables have turned ...
Here's the list of the reference tests that are failing after the subpixel layout was enabled on the GTK port:
Of course, the failures should be investigated.

The tests flagged in bug #122511 have a very similar issue to the previous one.
css3/flexbox/auto-margins.html is passing since r178063 which updates the test expectations. I will remove this bug from TestExpectations file.
According to https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/11947/steps/layout-test/logs/stdio fast/text/complex-initial-advance.html seems to pass.
Will update expectations.
It is fixed because the expectations was updated in r250884 (2019-Oct)
The https://webkit.org/b/206079 removes the expectation in GTK+ from platform/gtk/TestExpectations for related to this defect.
