# How the Problems Are Solved

Updated the css to set the overflow to hidden and text-overflow to
ellipsis, this is the simplest fix I could come up with, if you have a
better alternative feel free to tell me what you would prefer 🙏

# Additional Changes

None

# Additional Context

I couldn't test the following case locally since I had trouble setting
up a SMTP provider locally, but the class affected by my change should
also target this case, if someone could test it before merging it
