Shape annotations disappear at z19

[cammace]

When zooming in a high zoom levels polygons disappear. This potentially could be related to #5109.

What zoom level does it disappear at? (Turn on the tile boundary and tile info debug flags so it’s clear.)

[cammace]

greater then 20 zoom level and it disappears.

Is #4907 related?

Doesn't look like it, I just tested their style and was unable to reproduce.

@1ec5 @friedbunny @boundsj Is this reproducible on iOS or is this just an Android thing?

[1ec5]

I’m seeing this in iosapp on master at z19 and above, after choosing “Add Test Shapes” and zooming into the red triangle overlay over Oregon. The shapes reappear at z20. The issue also reproduces in iOS SDK v3.3.0-alpha.3.

UIView-backed annotations do appear at z19, as their placement is not dependent on mbgl. However, they cannot be selected because mbgl plays a role in hit testing.

Still reproduces following #5175.

👉 #5418.

I'm seeing this same issue on both our internal app (zoom level ~19) and on the Mapbox Dev Preview app (not sure what zoom level).

It looks like this fix won’t make it into the iOS SDK until v3.4.0, whereas we’re getting reports of the regression in v3.3.0 (#5715). @brunoabinader, how feasible would it be to backport a fix to the release-ios-v3.3.0 branch for v3.3.1?

I've backported the patch from e1be2c4 in release-ios-v3.3.0 branch: committed in 2a0e296 👍
