the clipboard could not be read; handle the paste event and pass event.clipboardData instead

Warnings reference › clipboard/no-read

Identifier: clipboard/no-read
Raised by: The grid (core)
Since: 1.6.0

What happened

The asynchronous clipboard read is unavailable or was denied - no navigator.clipboard, an insecure context, or the user refused permission. null is returned and nothing is pasted.

The fix

Read the clipboard from a real paste event, where the data is available without permission, and hand the text to the grid.

The smallest fix

el.addEventListener('paste', (e) => grid.clipboard.paste(e.clipboardData.getData('text/plain')));
