it should be disposed within event handler before calling this.handleCopy.

Can you explain why?

because we want to wait till copy event is fired and remove a listener only after it? I don't understand how current change ensures it, i.e. it removes a listener before calling copy.
We use the same pattern in other places as well: https://github.com/theia-ide/theia/blob/60dcb3326ea5e70c8d1017dcd206013304a5c92e/packages/markers/src/browser/problem/problem-contribution.ts#L158-L168

const toDispose = addClipboardListener(document.documentElement, 'copy', e => {
toDispose.dispose();
this.handleCopy(e, downloadUrl);
});

I am OK merging this, but then the static download link is gone. |

@kittaakos let's merge it and deal with #5707 separately? |
