Greg Stoll 6b9e711a99 Bug 1871135 - Add content analysis support to clipboard operations r=edgar,nika,masayuki,devtools-reviewers
When content analysis is on, pastes will be checked by the CA
agent while tab input is blocked. The synchronous nsIClipboard.getData()
method must block until the analysis result is received, so this
requires doing a SpinEventLoopUntil.
