Status: VERIFIED FIXED

(Fenix :: Browser Engine, defect)

Description

[Jonathan Almeida [:jonalmeida]]

Attachment: viewport.html

Steps to reproduce

1. Scroll down on the attached page viewport.html (test page taken from bug 1815657 but any site that has nested scrolling would work).
2. Scroll upward and in the same gesture, continue pulling upward more than the previous downward gesture from step 1.
3. Tap on the screen.

Expected behaviour

• Nothing happens.

Actual behaviour

• The Pull-To-Refresh throbber is activated.
• The throbber position is pulled down approximately the same distance as the over-scroll gesture from step 2.

Device information

• Firefox version: Firefox 122
• Android device model: All devices
• Android OS version: All versions

Any additional information?

• See attached video.
• Verified that this bug is a regression from bug 1847305 by reverting those patches and using the same STR.

The bug is marked as tracked for firefox122 (beta) and tracked for firefox123 (nightly). We have limited time to fix this, the soft freeze is in 13 days. However, the bug still isn't assigned.

:jonalmeida, could you please find an assignee for this tracked bug? Given that it is a regression and we know the cause, we could also simply backout the regressor. If you disagree with the tracking decision, please talk with the release managers.

:jonalmeida could this be triaged for Severity?
Do you have any options to address this for Fx122, I added tracking based on the description. Can we consider backing out the regressor from Fx122 to give more time to address this with Fx123? Though the regressor is an S2.

Settings has S3 for now because the pull-to-refresh feature is turned off by default in beta and release channels, so I am slightly less concerned about it.

Titouan and I are going to discuss this more tomorrow after some more investigation and impact analysis when we both have overlapping timezones to debug together.

Keeping NI for both of us until then.

We have a patch that will solve this bug without needing to back-out the regressor - see comment 8.

We will let it bake over the weekend in nightly and request an uplift for 122 early next week.

Comment 15

[BugBot [:suhaib / :marco/ :calixte]]

The patch landed in nightly and beta is affected.
:tthibaud, is this bug important enough to require an uplift?

• If yes, please nominate the patch for beta approval.
• If no, please set status-firefox122 to wontfix.

:tthibaud/:jonalemedia any concerns with adding an uplift request on this today?
Fenix 122.0b8 builds tomorrow. It would be good to include this now it's been verified and had a few days in Nightly.

Comment 17

[Jonathan Almeida [:jonalmeida]]

No, we're quite happy with the status of the patch, thanks for the reminder. Preparing an uplift request now.
