Description

When opening the block inserter on Android, the animation often flashes the blocker inserter UI onto the screen before subsequently hiding it and animating upwards into place. Occasionally, the block inserter will even render detached from the bottom of the screen, leaving it floating in the middle of the screen before animating downward into place.

The issue is fairly sporadic and difficult to reproduce consistently, at least the detached block inserter occurrence. It has been reproduced in the WPAndroid 17.3 beta build. It was not reproducible in the WPAndroid 17.2 Play Store build.

Step-by-step reproduction instructions

1. Launch the Gutenberg block editor in the WPAndroid app.
2. Tap the plus icon button to open the block inserter.
3. Close the block inserter.
4. Repeat the previous steps multiple times over.

Expected behaviour

The block inserter always animates into place sliding upwards.

Actual behaviour

The block inserter often flashes on the screen before animating. Occasionally animates downwards to the bottom of the screen.
