Creating a table sometimes insert empty lines between rows, breaking the table

[nathank (Nathan Kershaw)]

I’ve just been tripped up by this in my instance when creating a new table, but it doesn’t seem to happen here in Meta.

Actually - yes it does!!!

|Column 1 | Column 2|

|— | —|

The key issue is if that it happens when the cursor is not at the very bottom of the post.
