I replaced the CoreControls.js file with mine, but now there is a new issue:
When I create a Callout annotation, draw the two lines and type some text, the textbox jumps to the left side, although it should be placed where I put the text.
I attached a video to demonstrate it.
This bug didn’t occur with the old CoreControls.js, I just tested it.

It looks like there were some unintended changes between your version of 188.8.131.52541 and later versions, it caused this behavior. I quickly found the issue and fixed it and produced a new CoreControls.js file and sharing it with. Here is the link https://drive.google.com/file/d/1AH0Dz7Mxe_59f9wEz0TEhchw4NBq1HiA/view?usp=sharing
Sorry for the inconvenience!
