Prevent pressing escape when editing document name to bubble up to the editor (#3725)

This prevents pressing escape to bubble to up to editor when editing
document names. Prevents the current tool to change back to select tool.

### Before

Pressing escape when editing the name stops the editing, but also
switches from hand tool to select tool.

### After

We no longer switch to hand tool when we press escape the first time.
The second time it still works though.

@mimecuvalo happy to wait for your focus management PR to get merged,
then update accordingly by using `editor.focus()`.

### Test Plan

1. Edit document name.
2. Press escape. It should stop editing the document name, but should
not switch the active tool to select tool.
3. Pressing escape once again should do it though. Also keyboard
shortcuts should also work.

- [ ] Unit Tests
- [ ] End to end tests

### Release Notes

- Prevent escaping out of editing the document name to switch the active
tool to select tool.
