Typing should resume and your mouse cursor should be where you last left off (preferably within the [[ ]] and not outside it so that you can issue the | if you want to abbreviate the link name)
Actual result
The cursor is nowhere on the note. You have to manually click on the note to bring the cursor back
By the way, when I used a custom css, the cursor is on the note as (somewhat) expected (the cursor is outside of the []). See links below for the custom css that I added.
However, I do not think that this should be the expected result. The cursor should be inside the [] so that you can issue the | if you want to add a shortcut name.
