I suspect that the problem occurs due to a conflict between the double-tap gesture that zooms in on the map.

p. s. two years ago, I reported this in discussions #4414, but it seems issue was not opened

I can reproduce this. However, this is an upstream issue (in tangram-es) which will not get fixed. It will get fixed by moving to another map renderer, MapLibre. There is an open pull request in progress for this: Helium314#516 .

A, well, workaround is to not use the fling-gesture but tap-and-hold, use it like a slider. This works fine in tangram-es. TBH I didn't know a fling-gesture existed and not sure a fling-gesture for zooming exists in MapLibre.

In any case, this will not get fixed.
