Layer animations pending on bitrise

Description

A clear and concise description of what the bug is.

• I have tested this issue on the latest Detox release and it still reproduces

Reproduction

I have firebase analytics and performance in the app, last I had was detox version 17.14.9 and I did not have this problem. Ever since I updated to version 19.4.2 at some point my tests start failing by getting stuck with the message below:

detox[18542] INFO:  [APP_STATUS] The app is busy with the following tasks:
• There are 1 work items pending on the dispatch queue: "Main Queue (<OS_dispatch_queue_main: com.apple.main-thread>)".
• Run loop "Main Run Loop" is awake.
• UI elements are busy:
  - Layer animations pending: 1.

I watched with remote connection, the weird thing is there is no animation or anything like that happening, it just hangs in there. This happened for example when a new screen came into view and when I closed and reopened the screen by hand the tests actually resumed. There is a small loader when the screen first shows and then it disappears, but it does disappear after a very short time.

I haven’t experienced this locally yet. What could the reason be for this and can I work around it somehow? It’s just blocking me from updating detox for a while now.

Expected behavior

Tests should not get stuck when there is no animation happening.
