Loading online help puts focus on Help browser

When I load help from an online documentation source (from Atlassian Confluence) by overriding the Command.CommandContextHelpUrl property of a command, loading the content will put focus to the Help content in the browser. This means that any subsequent keyboard input gets sent to the Help page being displayed, not the running command.

Interestingly, this is not the case when default Rhino help is displayed.

Got it. This bug has been filed RH-20188
