Issue initially reported in https://github.com/mozilla-mobile/fenix/issues/9720. Swiping down on the page header I see the following data from GeckoView's `InputResultDetail` here[1]: - `inputResult` == `INPUT_HANDLING_UNKNOWN` (-1) - `scrolLDirections` == `SCROLL_DIRECTIONS_NONE` (0) - `overscrollDirections` == `OVERSCROLL_DIRECTIONS_VERTICAL` (2) Swiping down on the scrollbable content while at it's top I see the following data from GeckoView's `InputResultDetail` here[1]: `InputResultDetail` here[1]: - `inputResult` == `INPUT_HANDLED_CONTENT` (2) - `scrolLDirections` == `SCROLL_DIRECTIONS_BOTTOM` (4) - `overscrollDirections` == `OVERSCROLL_DIRECTIONS_HORIZONTAL | OVERSCROLL_DIRECTIONS_VERTICAL` (3) In this last case the values seem unexpected and they explain why also the toolbar does not respond to the scroll gestures. cc Botond for recommendations since we're in an active process of polishing the feature.

Note that on Chrome scrolls in the "Latest updates" section of the website will also scroll the header and then the toolbar / pull to refresh. cc Botond for recommendations since we're in an active process of polishing the feature.
