Issue with Worker that imports sth from vendor chunk

[maccesch]

Describe the bug

Everything works perfectly while developing. But after building I get

Uncaught ReferenceError: global is not defined
    at vendor.f5fc9a77.js:31 

Tracking down the error shows that it has to do with popper.js which is used by v-tooltip. Obviously it is not meant to be used in a worker context. But because the worker imports another library, which is also built into the vendor chunk, it is being executed on the worker.

Reproduction

Here you can find a minimal project reproducing the issue. v-tooltip is used in some component and the worker imports another library (doesn't matter which one).

Run vite build and serve the resulting files in folder dist. You will the see the above mentioned error in the browsers dev tools.

Thanks for the tip! Unfortunately it didn't change anything in my case.

Maybe try adding ?worker&inline or #2494

I can't seem to reproduce this. The repro worked fine for me without any errors, perhaps something was fixed in popperjs? Or perhaps the recent web workers improvement in Vite had fixed this. I'll close this for now, but feel free to let me know if the issue still persists and provide a repro along side.

We are no longer splitting the vendor chunk by default, so that may be the reason it works now
