Copying text to the description of a card triggers the "Unsaved Changes" leading to possible lost content on cards

Issue Summary

The main part of a card is its description. It's the place where all users can put additional information about the purpose of that card. However, for some customers who rely on copying text from different sources into the description of cards, this could result in the "Unsaved Changes" being triggered, resulting in potentially losing what they copied into their cards.

Steps to Reproduce

Based on multiple tests, we noticed that using multiple characters like dashes (----) and other types of markdown indicators coming from third-party apps will result in the text triggering the ‘Unsaved changes’ message after editing a card for the first time. 

Depending on the text formatting, this might also trigger when copying and pasting text from different sources.

Expected Results

Copying a text from a different source to the description box of a card and saving it shouldn't trigger the "Unsaved Changes" warning. 

Actual Results

Copying text from a different source to the description box of a card and saving it might trigger the "Unsaved Changes" warning, depending on how the text is formatted on the source.

Workaround

After saving the description for the first time, users will need to open the description in edit mode one more time and hit "Save" again. This will ensure the information pasted into the description is saved, and the "Unsaved Changes" warning isn't triggered.
