Linux specific: Fixed a bug focusing of the some settings tabs

Steps to repro of a bug:
1. FFF/SLA printer is selected
2. Load 3mf projet with SLA/FFF printer
3. Chnage printer to the FFF/SLA
=> (Print a Filanemt Settings)/(Print a Materials Settings) are disabled

Notes: This issue appeared after https://github.com/prusa3d/PrusaSlicer/commit/bfce4f6, when find_toplevel_parent(plater) instead of plater was set as a parent for ProgressDialogs
