Render bounds greyed out

[odedd]

It's a nitpicky one

If my render source is:
"Selected media items", "Selected media items via master", "Razor edit areas", "Razor edit areas via master" bounds is greyed out. Makes sense as there's only one option.

But if I then load a preset with any other source, the bounds selection remains disabled. Only when I click the source and select it again does it become enabled again.

[schwa]

Fixing, thanks for the report.
