Context menu clashes with Android's soft menu buttons

### Steps to reproduce

1. Long tap on a message
2. Observe the pretty context menu
3. The menu however has Android's switcher/home/back softbuttons overlaid at the bottom, which feels like a nasty clash of overlapping OS v app UI:

### Outcome

#### What did you expect?

Surely it should either overlay the buttons entirely, or the context menu shouldn't reach down that far.

#### What happened instead?

The fact that both UIs overlap and get entangled feels bleeeeeeurgh.
