This is related to #306 - This time the selection of Page Break block happens by the "user" with the cursor/tapping, instead of programatically like in #306, but the end result is the same.

Steps to repro:

• Tap on a para block
• Tap on the page break block
• The block holder is selected, but the soft keyboard is still up, and the caret blinking in the previous para block
• If you tap on the keyboard characters are inserted in the para block
