Replace series / Hit "escape" / Data is gone

The "replace series" option seems to immediately clear the screen: When I'm in the dialog the pane has already been cleared, and hitting "escape" does not undo the damage. After this, the pane is empty, but still has a context menu, with an hr at the top.

I don't think this is a big deal, but it's also not quite the behavior people would expect: Usually, nothing irrevocable is done on entry into a modal dialog.

Just "Replace Series"; "Replace Track" works as expected.

Note that the data is already gone in the background.

No data, and HR at the top of the menu.
