Error editing card comments

[Ricardo Penagos]

I have a comment that was edited last night at my house. When I get to my work and see the comment, it's fine. But when I click Edit it shows me previous content, it is not the latest content. 

Steps to reproduce the issue (on the Trello website):

1. Create a card

2. Create a comment

3. Edit the comment (it can be at home for example).

4. Edit the same comment in another location (can be in the workplace)

Hi Ricardo, welcome to the Atlassian Community!

I tried to reproduce this issue, but it's working as expected for me.
If I edit the comment and close the card without clicking "Save", I will see the unsaved changes and have the option to save them or click "Discard changes" to revert to the previous version of the comment.
