Fixes: #98754

This will finally put an end to a thorn in my side.

Not too familiar with this part of the code, but the codestyle checks out

I tend to agree with this statement in the bug report:

In my humble opinion, this boolean shouldn't even be in the window there, but part of the export options, but that's perhaps more of a proposal than an issue report.

(Also with the fact that it's proposal material and thus not something to handle here.)

So until we do decide to change this, I agree with making the boolean on the export dialog persistent.

Thanks!
