Interactive scripts should use the context
palette or gradient rather than the saved
one, as the user is more likely wanting to
edit the gradient or palette they have
actively selected. This is also in line with
how 2.10 operated.
This patch clears out the palette or
gradient property of Python scripts
when the GUI is created, so that it
uses the context version. It does not
affect non-interactive usage.
