Description

When format on copy is enabled, a line is removed completely when pasting.

With my attempts, any file, only ones with pre-existing content, loses this line when pasting. The comment seems to be the issue as it doesn't happen without.

See here for demonstration:

Steps to reproduce

1. Enable format on copy and ensure biome is default formatter
2. Copy code
3. Go to a TS or JS file
4. Paste code
5. Line missing after formatting.

Expected behavior

I expect the file to format properly, or at least not lose a line I paste.

Does this issue occur when using the CLI directly?

Logs

None output during paste in output. Last output was the connection at 13:43, which is before when the video in the description starts.

Same problem with macos, but worse, not just losing a line, but the paste becomes garbled and loses all the code that follows.
I suspected vscode, but not the plugin. I spent an afternoon trying to solve this annoying problem, and finally by disabling plugins one by one (I have more than 100 plugins) finally determined that it was due to a bug in biome's vscode.

If others are experiencing this issue, until it is officially fixed, the following configuration can be used to mitigate it

{
 "editor.formatOnPaste": false,
}
