The first and second New Tab don't have a favicon
59.0a1 (2017-12-15) (64-Bit) macOS 10.12.6 STR: 1) Open a new window with three New Tabs Actual: New Tab #1 and #2 don't have a favicon. But #3 has it. Expected: All tabs should show it (or hide them at all) A screencast is attached. This seems to be recent regression from yesterdays build to today. Thanks.
The first new tab is about:home. The second new tab is not preloaded.
Looks like the icon is first appearing then disappearing?
Sorry, in comment 1 I meant to clarify that the first tab about:home (never preloaded) and second tab is about:newtab (not preloaded). Subbsequent about:newtab opened after the first about:newtab should be preloaded. So probably something about preloaded about:newtabs not triggering some code path that happens for "regular" page loads.?
(In reply to Ed Lee :Mardak from comment #2) > Looks like the icon is first appearing then disappearing? Yes, correct. It appears and disappears again.
johannh, I would guess from comment 3 that some default icon behavior is happening when the page loads "normally" (e.g., to clear the icon if a regular website doesn't have an icon ??). Preloaded pages are already loaded, so they don't trigger the usual progress listeners.
Just only for your information: It seems that it does not happen only on the first and second new tab. The favicon also disappears, if you open some new tab quickly in succession. A screencast is attached. Thanks for looking into it.
