Comments not saved in Block Editor when using Firefox browser

Hi,

I am using MIT App Inventor 2 in the Firefox browser.
My operating system is Debian version 12.

I removed all Firefox browser extensions but Tampermonkey.
I cleared browser's cache.

These are steps that I am doing when adding a comment to a block:

  1. I add a comment to a block by right click on to the block.
  2. Enter text in to the comment field.
  3. Close the Comment.
  4. Open the Comment and there is no text at all.

Is there a solution for this behavior?

Any advices will be appreciated!

Let us attempt to identify where the issue lies...

Which AppInventor server are you using? ai2, code, ai2-test ?

Try with a private browsing window (no extensions) do you get the same behaviour?

Try with Chrome ? (Works for me on Xubuntu 24.04.02 LTS)

[EDIT]
Just tested with ai2 server on Firefox 141 - I see the same behaviour

I have found if I type text into the comment box,leave it open, return to the projects list, then return to the project - the comment text is still there, and can be closed and opened to see the text again. Not ideal...

Same behavior with Chrome here.

You don't even have to return to the project list. Simply move the block or block structure in which the comment was inserted slightly.

Here's what I get on Brave, Windows 10, with existing comments from Do It:
sample run

What I am seeing is that closed comments, upon return to the Project from the Projects list, are reshaped and have their cursor positioned to the end, presenting the appearance of having lost text until you reshape the comment bubble by dragging its lower right corner.

I am using ai2 MIT AppInventor server, the ai2 not the ai2-test.

Already tried with a private browsing window (and no extensions), still get the same behavior.

I just installed on my Debian 12 the Google Chrome and in it adding comments to blocks works fine.
