Leak in GleapInvisibleActivityManager

[ggueno]

I found a memory leak associated with GleapInvisibleActivityManager leading to the main activity of the app being retained because a reference to the view is kept in GleapInvisibleActivityManager (from what I understand)

Here is a project I made to reproduce it (with leak canary)
gleap-leak.zip

I'm using the last version of Gleap SDK - 13.6.1
