Describe the bug
After an upgrade to the last chrome version, the execCommand break the copy during the Copy/Paste action.
Maybe now deprecated function now on Chrome, still work on Firefox i think.

Your environment details

• Device: Desktop
• OS: Linux
• Browser Chrome 134

Quick find

The handleCopy file use on line 23 and 24: document.execCommand("copy")
The handlePast retrieve it on 14: event.clipboardData.getData("text/html")

Copy could be replace by

If ("clipboard" in navigator)
  await navigator.clipboard.writeText(div.innerHTML)
else
  document.execCommand("copy")

Past could be replace by the same logic but with:

  const data = await navigator.clipboard.readText()

Im not sure about the handlePaste //TODO line and the way it required information from the dom.
But for the else logic, we could maybe use the the readText one.
