I'm doing a test where I have to simulate the user's action when doing ctrl+A (a paragraph is automatically selected) and then ctrl+C to check that the content of the clipboard is the same as the selected text.
To do this, I have tried to do this:

const codeText = await this.page.codeText.innerText()
  await this.page.context().grantPermissions(["clipboard-write"])
  await this.page.codeText.focus()

  await this.page.keyboard.press("Control+A")
  await this.page.keyboard.press("Control+C")
...

This test works when I run it inside a docker container using Linux.

The problem is when I try to run this same test in a macOS environment. To do so, the only thing that changes is Control+A for Meta+A and the same for C.

const codeText = await this.page.codeText.innerText()
  await this.page.context().grantPermissions(["clipboard-write"])
  await this.page.codeText.focus()

  await this.page.keyboard.press("Meta+A")
  await this.page.keyboard.press("Meta+C")
...

I have checked that Meta+A selects the text correctly, but Meta+C does not save the selected content to the clipboard.

Is there a reason for this or is it a bug?

For the record: copy shortcut does not work:

• WebKit WPE
• WebKit on MacOS (at least headless)

Requires further investigation

For the record number 2: Undo shortcut does not work:

• WebKit WPE && GTK
