The following workaround seems to provide working links:
- Paste the link you wish would work into your reply.
- Highlight the colon (‘:’) character in the link.
- Click the ‘B’ for Bold font option.
- The above will surround your colon with two pairs of asterisks (‘**’).

The result looks a bit funny, but at least in my browser, clicks right away to the desired destination.
