Expected Behavior

Right clicking a custom browser dock should always bring up the right click menu.

Current Behavior

After docking the dock into the main window, and until it is restarted, right clicking the dock doesn't cause anything to visibly happen.
Undocking doesn't restore the behaviour, only restarting obs.

Steps to Reproduce

1. Create a new custom browser dock
2. Verify that right clicking it brings up the relevant menu
3. Dock it in the main window
4. Verify that right clicking it does nothing

Anything else we should know?

• alt-tabbing back and forth causes the same
• Right clicking through the remote debugging devtools does correctly spawn the menu
