Fix nearby leaks, at least some ot them

[neslihanturan]

Description

Fixes #1368 , current leaks. Currently I could only reproduce C, it took too much time to be able to reproduce it. A and B is same, and It seems like E and F is something we can ignore: https://medium.com/@amitshekhar/android-memory-leaks-inputmethodmanager-solved-a6f2fe1d1348

Since we have already solved B (also A) and D, we should only have C
