Yes, browsers being native apps don’t. It’s an opinionated aspect, but when you select text on mobile, it forcefully scrolls to the selection, and your whole UX or animations could break.

 

Respectfully, which mobile browser force scrolls when you select text? On iOS for example the only time force scroll happens is when inputs are focussed. There is a strong business case for accessibility w3.org/WAI/business-case. Fluid animation is achievable with many front-end frameworks for example PopMotion Pose that wouldn't break with scrolling. If visual styling is the issue you can also style the text-highlight colour, or remove text selection for certain elements (not the whole body, or even create your own text selection or sharing interface Medium.com style

Safari on iOS.

Yes, you're right about removing selections not for the body ,but I still think that mobile user don't really need to select any text of your interface. For example, if you're building Twitter, enable text selection only for tweets.

Yes that's a nice solution, this way there's still some accessibility, it's worth mentioning that when viewing an individual post on Twitter text selection is allowed
