App is fine, all other gsap animations are working. And I use context cleaning already. This app is for WordPress which has additional react functionality, I guess that problem is because text is inside Richtext editor, which also manipulates text. Unfortunately, I can't make any kind of demo so I can't see how you can help. It's not very critical in current point.
I fount temporal fix. Instead of dealing with text, I just check if block has inner div and simply change textobject for something like textobj.querySelector('div')
This works, but unfortunately, GSAP makes more lines. When I have 2 lines of text, it's making 4 lines and here I gave up. Better to keep previous logic when whole block is line, it's not so critical like wrong line break
