Fantastic news e8ea7073596c ! Thank you for catching up on this one ! Not sure that my message in a bottle at sea send by mail yesterday is a coincidence but anyways it is good to have a feedback.
I look forward for a fix
Please note that this issue is in Jira but is also present in Trello's comments and it's very annoying. Its even worsened by a text edit feature which prompts the emoji shortcut list whenever typing ":" (which happens all the time)
More info on this request : https://support.atlassian.com/requests/TRELLO-171402/  (Not sure is there are other tickets related - we have no rights to view the issue links)
Please consider linking both issues and maybe editing the problem description in this ticket.

There are a lot of people in our team waiting for this fix.

Thanks for taking ownership of this issue.

Thank you e8ea7073596c for responding.

I do hope that there can be some priority given to this issue. Please note this ticket is over 4 years old and there is no work around. 

Hi everyone,

Thank you for your patience. I’m one of the product managers on the Editor team, and I’ll be taking ownership of this ticket moving forward. We’ll be considering it for review in the next planning cycle. While I can’t provide a firm commitment at this stage, I want to reassure you that we’re not overlooking this. We will re-evaluate our roadmap in the coming months. In the mean time, feel free to provide any constructive feedback in the thread.

Thanks again for your understanding!

I just send an email to a handfull of mails of people working on Atlassian products which I managed to found email addresses online. 
Hopefully one of them will actually care to have this ticket back on the workflow.
Desperate times calls for desperate measures, the ticket is older than my daughter !
Fingers crossed !

1965e5c0a44d It appears that the reporter/assignee no longer are part of this team. We're trying to find anyone from atlassian that can address this ticket. It's over 4yrs old and not one response. 

Please fix this. When copying/pasting emails/writing into the comment section it uses double spaces. You can't use Shift Enter to stop this so have to manually go through and backspace the extra lines.

please fix this issue

The workaround is ineffective when you have lists.

The default spacing makes certain formatting take up WAY too much space.
