Stable tests

Test	Result	Subtests	Kind	Description
`async-clipboard-read-unsanitized-null.https.html`	Pass	1 / 1
`async-html-script-removal.https.html`	Pass	1 / 1
`async-navigator-clipboard-basics.https.html`	Fail	16 / 17	TEST BUG	the test expects `write()` of an `image/png` representation whose data is a string to reject with a `TypeError` (Chromium): the string is the data of the representation (https://w3c.github.io/clipboard-apis/#dom-clipboard-write), and it is rejected with a `DataError` because it is not a PNG image, as `async-write-image-read-image.https.html` expects for a blob

`detached-iframe/write-on-detaching-iframe.https.html`	Pass	1 / 1
`detached-iframe/write-read-on-detached-iframe.https.html`	Fail	0 / 1	TEST BUG	the tests expect `read()`, `write()`, `readText()` and `writeText()` of the clipboard of a detached iframe to return `undefined` (the Chromium bindings do not run the operations of a destroyed execution context): these operations return a promise (https://w3c.github.io/clipboard-apis/#clipboard-interface), which is rejected with a `NotAllowedError` because the document is not fully active
`detached-iframe/writeText-readText-on-detached-iframe.https.html`	Fail	0 / 1	TEST BUG	the tests expect `read()`, `write()`, `readText()` and `writeText()` of the clipboard of a detached iframe to return `undefined` (the Chromium bindings do not run the operations of a destroyed execution context): these operations return a promise (https://w3c.github.io/clipboard-apis/#clipboard-interface), which is rejected with a `NotAllowedError` because the document is not fully active

`permissions/readText-denied.https.html`	Pass	1 / 1
`permissions/readText-granted.https.html`	Fail	0 / 1	TEST RUNNER	the clipboard is empty when the test starts, so `readText()` rejects with `NotFoundError` (the test assumes the system clipboard holds text)

`permissions/writeText-granted.https.html`	Pass	1 / 1
`text-write-read/async-write-read.https.html`	Pass	5 / 5

`async-custom-formats-write-read.tentative.https.html`	Pass	1 / 1
`async-navigator-clipboard-change-event.tentative.https.html`	Fail	5 / 7	NOT IMPLEMENTED	the `onclipboardchange` event handler attribute of `Clipboard` (the event is fired to the listeners only)
`async-navigator-clipboard-write-multiple.tentative.https.sub.html`	Timeout	0 / 4	NOT IMPLEMENTED	a new `clipboard.write()` does not reject the pending one with `NotAllowedError` (the test waits for the pending promise)
`async-svg-read-write.tentative.https.html`	Fail	0 / 1	TEST BUG	the single subtest also expects the inline style that the Chromium read-time sanitizer adds to the `<svg>` element (`color: rgb(0, 0, 0); font-size: medium; ...`, the computed style of the copied content), which no specification defines
`async-unsanitized-html-formats-write-read.tentative.https.html`	Fail	0 / 1	NOT IMPLEMENTED	inlining the computed style of the elements in the unsanitized `text/html` read (a Chromium-specific expectation)

`permissions-policy/clipboard-read/clipboard-read-enabled-by-permissions-policy.tentative.https.sub.html`	Fail	1 / 2	TEST RUNNER	the clipboard is empty so `readText()` rejects with `NotFoundError` in the top-level document (the policy allows it)
`permissions-policy/clipboard-read/clipboard-read-enabled-on-self-origin-by-permissions-policy.tentative.https.sub.html`	Fail	2 / 3	TEST RUNNER	the clipboard is empty so `readText()` rejects with `NotFoundError` in the top-level document (the policy allows it)
