Email All Members Formatting Issues and Errors

When composing an email using Email All Members and pasting from a Google Doc I initially received an error 500 on reviewing the form.

After some adjustments the error stopped happening (don't know why), but there were several formatting issues reflected in the output not visible in the preview.

I can provide the document I pasted from if that's useful, but the results have been inconsistently reproducible.

Additionally in one case I selected some text that had been implicitly made and hit the link button to change the link text, upon submitting the link dialog the link moved from where it was in the docuemtn to below the bottom of the text area where it could not be selected. Upon reloading the page (restoring the message) the URL of the link was appended to the end of the message and selectable again.

Start with the Email All Members compose, review, and submit flow, using pasted Google Docs content to investigate the reported 500 error and inconsistent formatting. Check the link-editing case where the link moves below the text area and the URL is appended after reload. Done means the flow handles pasted content consistently, preserves formatting and link placement, and no longer produces the review error.
