TYPO3 Core

It happens only when you just use: 'defaultExtras' => 'richtext[]' for the RTE field, so my description was incomplete. When you use 'defaultExtras' => richtext:rte_transform[mode=ts_css] it's all fine.

As of https://docs.typo3.org/typo3cms/CoreApiReference/Rte/Transformations/Overview/Index.html#meta-transformations mode=ts_css is the recommended configuration

This is correct but why would no RTE transformation mode change the editors input in the described way? Seems to be a bug.

Hi, can you tell us more about how to reproduce this?

- What browser are you using?
- Are you using CSS Styled Content or Fluid Styled Content?
- Are you using the default RTE configuration or a custom one?

I tried with both 7.6.0 and the latest master from Git and I can't reproduce it. Tested with Chrome, Firefox and Safari on MAC

The appended newlines are stored in the database. I've tested this with no transform mode configured in the TCA ( 'defaultExtras' => 'richtext[]') on a fresh install of the current develop. The used browser for the backend doesn't seem to make any difference.

Same here. And when I use 'defaultExtras' => richtext:rte_transform[mode=ts_css] it does not insert new lines, but instead it inserts:
<p> </p>

Maybe it has todo with: https://forge.typo3.org/issues/45527.
