fix: fix hmr of dynamically loaded vue sfc modules in apps with tailwind

[unshame]

Description

Fix #701

Should I try adding a test for this? It would be way more complicated than the tailwind tests I currently see in the repo. I can try adding a new playground for tailwind 4 and test this there.
