ctml Unfortunately, no. I do not have a live site which has this issue(actually, I did not install/enable this extension anymore). And I was thinking about, if I do, I will reply the developer.
@askvortsov Hi, I got a live site now, if you can please take a look. You can see the overlaps of the css. I just disabled the Rich Text extension. Feel free to let me know if you want to take a look, I will enabled it.
