@lucaboesch Just removing the CSS value would very likely change the behavior of existing content after updating.

If people got used to the bug (as I did), they would not click on the center button anymore but rely on content being centered either way. If you now just take away that styling, the text would be left aligned.

I think In addition you should also have to take care of existing contents first by updating them via H5P's upgrade mechanism. You could center them for real in HTML. This way, people could change the alignment to left or right themselves if they want to by editing the content after the upgrade - but their existing content will not break forcing them to manually change everything back to centered.

I have done the same for Dialogcards in case you want to see a reference: https://github.com/h5p/h5p-dialogcards/pull/96/files
