Re: [w3c/clipboard-apis] Should reading the clipboard throw DataError or empty clipboard items? (Issue #179)

RESOLUTION: Keep the exception during `write()`, but return empty `ClipboardItem` during `read()` if system clipboard is empty.

[17:26] <snianu> can you hear me?
[17:26] <whsieh> snianu: audio issues, let's move on for now
[17:26] <whsieh> snianu: nvm audio issues fixed!
[17:27] <whsieh> snianu: if clipboard item is empty and developer writes to clipboard, the write will throw an exception in Chrome but FF/WebKit allows that
[17:28] <whsieh> s/clipboard item is empty/clipboard item list is empty/
[17:28] <whsieh> snianu: creates confusion for web dev since it's unclear if they need to retry, or…

[17:29] <whsieh> snianu: read should not throw exception, write should throw exception
[17:30] <whsieh> snianu: with current DT APIs dev cannot clear clipboard by writing
[17:30] <whsieh> snianu: with async clipboard API you can write empty item (?)
[17:30] <whsieh> snianu: maybe flag to indicate that clipboard item is intentionally "empty"
[17:30] <whsieh> q+
[17:32] <whsieh> whsieh: if we want to expose a "clear clipboard" API, it should probably be navigator.clipboard.clear() or something
[17:33] <whsieh> johanneswilm: seems we're all in agreement
[17:33] <whsieh> sanketj_: to summarize, allow read empty items
