This bug has been revealed after enabling complex text by default in GTK and WPE ports in r221909.
Created attachment 320647 [details] Patch It doesn't fix all the failures after r221909, but many of them and produces results similar to the mac ones in others. I still need to investigate the weird space issues.
Comment on attachment 320647 [details] Patch r=me because this is the path to a better future, but this exacerbates our complex text selection rendering glitch, bug #148220. You can see that some of the expected results are now worse than before. E.g. editing/selection/select-across-readonly-input-4 shows the issue clearly.

To be clear, I mean r221909 has exacerbated bug #148220. Not this patch. I assume this patch is fine, but I don't know because I don't understand it. I'm just approving it because we have no font reviewers.

At some point we should do https://bugs.webkit.org/show_bug.cgi?id=167566.
