1816102 - Pull to refresh activates in Figma

Status: RESOLVED FIXED

(Fenix :: General, defect, P2)

Description

[Petru-Mugurel Lingurar [:petru]]

Similar to #1815732 but happens more often and to a higher degree. I was even able to trigger pull to refresh while in the middle of the page.
Testing in Fenix I see there are cases in which when we try to sync with GeckoView through InputResultDetail about how the touch was handled we can get multiple times in a row the following the following details here[1] based on which the app will show the pull to refresh throbber:

    inputResult == INPUT_HANDLING_UNKNOWN (-1)
    scrolLDirections == SCROLL_DIRECTIONS_NONE (0)
    overscrollDirections == OVERSCROLL_DIRECTIONS_VERTICAL (2)

Given that this issue depends on fast scrolls I think the issue has more to do with the time APZ needs to infer the touch result.

S3 since the issue happens on a particular website and depends on fast scroll and so a workaround exists.

I was not able to reproduce this issue anymore on the latest Fenix Nightly 124.0a1 from 2/2, using a Google Pixel 6 (Android 14).
I'll close this ticket as resolved.
