Gradient fill seems to detach from text if text is modified by contouring tool. This issue does not seem to affect other shapes.
Select Text tool, set font size to say 100, Add some text
Select gradient tool, select text and apply a gradient fill to text
Select move tool and move text around. Text will move with gradient attached as expected.
Now select Contour tool, add contour to text of say 5 pt radius
Select move tool and move text around. Text will move but now gradient appears to be detached.
From this point, the gradient appears to be a static background. Changes to the gradient are a bit unpredictable i.e. scaling or adding and moving gradient handles do not seem to align with gradient colours.
Now select text and set contour radius back to zero - gradient seems to reattach and text can be moved with gradient attached as expected. Gradient edits can be made as expected.
This same sequence on a shape does not exhibit the same “detachment” issue.
