Parentheses prevent new line in cards created via Email to Board (E2B)

Issue Summary

When composing a card with Email to Board (E2B), the card back description does not preserve the original email formatting if new lines ('\n') are preceded by parentheses. This causes the new line to be disregarded and the format of the original email to differ from the card back description.

Steps to Reproduce

1. Create an email with specific formatting, making sure to use parentheses before a new line.
   
2. Create a card from this email with the Email to Board (E2B) feature.

Expected Results

The card back description should have the exact same formatting as the original email, maintaining the correct placement of new lines and how they are handled.

Actual Results

The card back description shows differences in the email format when a new line is preceded by parentheses.
