#38934 ui: unreliable parent component scroll disable

noticed this on augmented road view that when swiping to the left to bookmark a route that the onroad view itself moves very briefly.

this causes the onroad view to sometimes move when opening the bookmark.

this issue itself is not super debilitating, but the underlying issue that a child component cannot reliably disable the parent gesture is.

this can be fixed by better event bubbling from child -> parent and most likely should be incorporated in the change described here: https://github.com/commaai/openpilot/pull/35526#issuecomment-3010319266
