Fixes #3834. Fixes regression so that review editor to work properly
with mobile views coordinating with the with Scenes palette. Regressions
were due to code cleanups. 22f74d32755c5e6a84da3f4899e5f80ac09415a1 did
not properly bind a function to "this".
60aae72ac55c7149f86c48a86785e1073e627de removed the global namespace for
review's Context.js class, but that caused its declaredClass to get
inherited value of davinci.ve.Context, which messed up some of our
(very ugly) IF tests. I thought about cleaning up those IF tests but I
saw about 100 different spots in code, and it's too late in cycle to do
that massive of a cleanup, so just reverted the old ugliness.
