Describe your issue

The Vite plugin intends to ignore SVG files that contain a ? or # in the path because Vite crashes when scanning those. The current regex only matches when ? or # appear before “.svg” and the string ends with “.svg”, so common paths like icons/foo.svg?component or icons/foo.svg#sprite are not ignored and can crash Vite.
Steps to reproduce:

Create a Vite project and enable the Tailwind Vite plugin from this repo.
Import an SVG with a query or hash, e.g. import Icon from './icons/foo.svg?component'.
Start dev server and modify the SVG; Vite may crash due to scanning.
Expected:

Files ending in .svg, optionally followed by ?… or #…, should be ignored by addWatchFile to avoid the known Vite crash.
Actual:

Paths like foo.svg?component or foo.svg#sprite are not matched by the ignore check and remain watched.

The bug in Vite is due to those characters in the path portion of the filename. It's since been fixed but the check is there for older Vite versions.

… Vite may crash due to scanning.

If you have a reproduction of this behavior please provide one and I'll take another look.
