Tables and Checkbox Glitches

[WeCanLearnAnything 100]

I made a video of three glitches involving tables and checkboxes.

1. The border disappears when checkboxes are added to empty cells at the bottom of a table.
2. It sometimes takes 2 clicks to place the cursor in the table after checking a box.
3. Two fast clicks sometimes presses down a bunch of formatting buttons.

Here's a Dropbox link to the video. I'll keep the link alive for at least a few days.

In creating the video, I found that sometimes the glitches happened and sometimes they did not. In fact, a fourth glitch I found is that sometimes clicking inside the table will put the cursor on the top left of the note. I was not able to reproduce this in a video, though.
