Adjust subplot param

I am no expert, but I think this is a fairly simple thing to solve that could contribute to the overall enhancement of the plot() function.
Running the commands bellow a figure is produced.

If in said figure the 'adjust subplot param' icon is clicked displaying the 'adjust subplot param' control bars and the figure is closed before the 'adjust subplot param' window, Julia crashes.
I don't think this is particularly urgent or difficult to fix, but since it happen to me, as a way of saying thank you, I thought I should point it out so that the Package becomes even better.
