1580072 - History manipulation intervention

Status: RESOLVED DUPLICATE of bug 1515073

(Core :: DOM: Navigation, enhancement)

Description

[Karl Dubost💡 :karlcow]

Not sure this is the right component.

See https://github.com/WICG/interventions/issues/21
and https://groups.google.com/a/chromium.org/forum/?#!msg/blink-dev/T8d4_BRb2xQ/WSdOiOFcBAAJ
https://bugs.chromium.org/p/chromium/issues/detail?id=907167

for background reading.

What's happening:

1. A user goes to a site.
2. The site creates two entries in the history
3. The user taps/clicks the back browser button

Expected:
The users expect to return to the previous screen they have actually seen

Actual:
The users go to the previous page in the history (which sometimes recreates an entry on reload).

This creates webcompat report because it doesn't meet the expectations and/or it doesn't behave the same than in chrome.
