The kernel would probably statically link it.

…wouldn’t that have the effect of bringing this code back into the kernel’s address space?

The code itself would be in the kernel, but the "parsing while mousing over" invocation would be on userspace code.

That is, the parse logic could be a library linked by multiple application.
