vite-error-overlay custom element can not be registered more than once

[lovetingyuan]

vite/packages/vite/src/client/overlay.ts

Line 185 in 43150e3

customElements.define(overlayId, ErrorOverlay)

should be changed like this:

if (!customElements.get(overlayId)) {
  customElements.define(overlayId, ErrorOverlay)
}

Is any contributors willing to resolve it? Thanks very much.

Is this related to issue #2478 ? I added a comment there mentioning how I noticed the client seems to be loading twice when using a backend integration

[lovetingyuan]

yes, it is the identical issue.
