Hi,
This extension appears to be blocking/capturing keyboard shortcuts preventing them from working in web apps loaded in tabs.
Main example is the Slack web shortcut shift+cmd+u for linking highlighted text. When I disable this extension it works. When the extension is enabled it does not.
At lest some other shortcuts in Slack web work. So it's not blocking everything.
I've looked around in extension settings and cannot see anything obvious I can configure.
