`new URL(foo, import.meta.url)` doesn't work when dependency was optimized

Describe the bug

Now, i use wasm-pack for build WASM file and WASM with JavaScript glue layer like this。

The glue layer code contains below code

if (typeof input === 'undefined') {
165 | input = new URL('color_thief_wasm_bg.wasm', import.meta.url);
166 | }

In Vite, after esbuild optimize third party, import.meta.url cannot be optimize succeed. Ref Vite Docs, even if set build.target to es2020 is still the problem

After preprocess

node_modules/color-thief-wasm-web/color_thief_wasm.js will be transform to node_modules/.vite/deps/color_thief_wasm.js which load .wasm file by import.meta.url receive incorrect path is node_modules/.vite/deps/xxx.wasm finally, the correct path is node_modules/color-thief-wasm-web/xxx.wasm

One of the solutions is set optimizeDeps.exclude to exclude third party module like this

An ugly practice is move wasm package to current project rather than node_modules for get correct path
