Difficulties to add text after a block node at the end

[cbratschi]

Describe the Bug

If a block node is at the end it is difficult to add new text after the block. Positioning the cursor above the block and using the down arrow key to navigate below the block works sometimes but often the cursor suddenly disappears. Pressing enter still creates a new paragraph most of the time.

Workaround is to use the plus button at the left to add a new paragraph after the block.
