Yes.

Describe the issue you encountered:
I'm not sure why this is but none of the right-click functionality works in our devtools. Maybe we're swallowing the onClick event? There are a lot of tools that I can't access at the moment.

Expected behavior:

Right clicking should open context menus for each devtools panel.

• Platform (Win7, 8, 10? macOS? Linux distro?):

macOS

• Brave Version:
  0.12.0
• Steps to reproduce:
  1. Open devtools (cmd+option+i)
  2. Try right clicking
• Screenshot if needed:

Here is an example of what you get on Chrome
