Issue with adding multiple indicators to a "panel" below the charts

I don't believe this is working as it should.

Best explained through an example with steps on how to reproduce:

1. Open up any chart. Doesn't matter
2. Add a new “Linear regression slope” indicator. Select to add it to “New Panel”. Choose any source and Period.
3. Now go back and add a second “linear regression slope” indicator and follow these steps precisely:
   • from the “Panel” drop down, select “Panel 1” (the one you just added)
   • change the periods from the default of “9” to something else

WHAMMO! The “Panel” selection resets, and users have to select it again. That is not convenient for users, nor is it “expected' behavior. As a user, when I select a panel, I shouldn't have to go back and select the Panel again if I change the ”Source" or “Periods”.
