Bug 282409 – REGRESSION(285310@main): [GTK] Cannot open links on various websites

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Michael Catanzaro]

Using Epiphany with WebKitGTK 2.47.1, visit: https://www.reddit.com/r/news/comments/1ggpaiu/rapper_young_thug_accepts_plea_deal_in_georgia/

Click on the "abcnews.go.com" link (which actually goes to https://abcnews.go.com/US/rapper-young-thug-accepts-plea-deal-georgia-rico/story?id=115370318), underneath the image

Observe that Epiphany opens an empty tab instead of loading the page as expected.

It works fine if you right click the link and select Open Link in New Tab.

[Michael Catanzaro]

(Interestingly, attempting to close the Blank Page causes the Epiphany UI process to crash, but that's surely a separate bug.)

[Michael Catanzaro]

This UI process crash occurs if the Blank Page is closed *after* its opener page. Epiphany assumes that the opener view is not destroyed before the new view is ready to show. Arguably this is an error, because the user might have a superhuman reaction time, but realistically I'd say this is WebKit's fault for emitting ready-to-show late.

I guess related pages are broken, probably after a site isolation related commit.

FYI, the issue appeared for me between

and

Confirmed.  Reverting 285310@main cleared this issue for me.
