Maybe we can do it in TextLayout in GPUI:
fda6eda3c2/crates/gpui/src/elements/text.rs (L309)
## Demo
https://github.com/user-attachments/assets/abbebee7-df8f-4067-86a7-15bc1a4c44cd
## Todo
- [x] Test for HTML View.
- [x] CodeBlock selection support.
- [x] Selection lines sometimes incorrect.
- [x] Listener Bounds changed to unselect.
