Issue Summary

This is reproducible on Data Center: (yes) / (no)

Reproducable in Trello Desktop version Trello 2.14.7-815

Steps to Reproduce

1. Create a card
2. Add a long description that you'd need to scroll to see all of
3. With the top of the editor visible, try to format text or add a list to the description -> this will work 
4. Now scroll down so the top of the editor isn't visible anymore but the formatting options are fixed to the top of the window and try to format text or add a list again

Expected Results

It should be possible to format text regardless of how far down a card description you've scrolled

Actual Results

Trying to add formatting while not scrolled up to the top of the Editor causes the card to close and Trello returns to the board view.

Workaround

• Keyboard shortcuts work to add formatting at any point
• You can highlight or move the cursor to where you want to add formatting, then scroll to the top of the description and add the formatting without any troubles
