"Text part language" Why is Arabic not starting from the right?？

📝 I used the Text part language function but the text always starts from the left. I found that the dir at the top of the editor is always ltr. How to set this to auto

Hi, thanks for the report. Current implementation of Text part language plugin unfortunately doesn't allow to change direction of text fragments/blocks. There is a feature request for this - feel free to add there anything you find important and add 👍 to increase its popularity.
If you want to set the content's language/direction, please refer to the docs on UI language.
