"Click to add cell" button breaks command mode when it's focused

[weibeld]

Description

"Click to add cell" button breaks command mode when navigating past the last cell with J.

When navigating past the last cell, the "Click to add cell" button appears and gets focused. After that, it's not possible anymore to move the focus to another cell with e.g. K or any other key combination.

Reproduce

1. Open new Jupyter notebook
2. Create new cell with B
3. Navigate past last cell with J, J

The "Click to add cell" button appears and no command mode key combinations can be used anymore.

Expected behavior

Should be able to navigate back to previous cells with K.

@weibel this was fixed in v7.0.6 released over a week ago, but you are using 7.0.2. Please upgrade your installation.
