+Subject: fix: expose globals to allow patching Devtools dock
+
+Electron calls into UI.DockController.instance().setDockSide(side) in
+order to allow users to set the devtools dock position via
+webContents.openDevTools({ mode }). In https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/3310870
+the globals which we used to enable this were removed, and so we need to
+re-expose them to fix this broken functionality. We should look to
+upstream a more durable approach to allowing us to do this, at which
+point this patch can be removed.
