1688279 - Support strings as data in ClipboardItem

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, task, P2)

Description

[Tom S]

The initial implementation in Bug 1619947 only supports Blob. We want to supports strings as well. This reduces the required string copies when doing clipboard.writeText again.

I have a patch that seems to work well enough. There is one open question for me about doing copying images to the clipboard via strings. This seems to always fail. I suspect this is just not possible with UTF-8? We should probably just not allow this.

Testcase:

  let res = await fetch(`test.png`);
  var item = new ClipboardItem({
    'image/png': (await res.text())
  });
  await navigator.clipboard.write([item]);
