Not sure if this a recent issue, or has always been the case:
When editing hyperlinks in the web interface (in a message), if the user just makes a change in a link due to a typo, the actual hyperlink doesn't change.
I know the proper way to do it actually edit the hyperlink (which allows you to edit both the text and the hyperlink), but users just change the text on the screen and assume the underlying URL has been updated.
Shouldn't the hyperlinks be updated to match the text once the user hits Send? (Like every other email client)
