1670933 - Back button is not enabled by iframe navigation when Fission is enabled

Status: RESOLVED FIXED

(Core :: DOM: Navigation, defect, P1)

Description

[Johann Hofmann [:johannh]]

STR:

• Enable Fission
• Open https://joo.uber.space/back-button in a new tab without any extra session history entries before it (i.e. directly "open link in a new tab" via the context menu, don't open about:newtab first)
• On the page, use the links and buttons in the iframe at the bottom to add navigations to that iframe.
• Note that the back button isn't getting enabled. It should be enabled because there's session history to go back to now.

When you hover the history.back() button in the iframe for 3s the back button will be enabled and it looks like all session history is kept correctly, the history change event just seems to be not propagated correctly.
