Unable to load multiple files

[justinroyboulanger]

Cura Version

5.4.0

Operating System

Windows 10

Printer

CR-10 pro

Reproduction steps

Open file previously could open multiple different files at once and arrange them on the build plate.

With the new 5.4 I need to open file for each different model i'll be placing on the build plate.

Steps :
File > Open file(s) (ctrl+O)
Try to select more than 1 .stl file

Actual results

Only one file can be selected. Manually entering the Path of multiple files like "file.stl" + "file.stl" still works.

Expected results

Multiple files should be selected

Thanks for the report.
This bug has been reported previously ( #15879 and #16003 ) so I'll mark this as a duplicate and go ahead and close this. I hope you understand.
You can still drag and drop multiple files but the "Open File" dialog doesn't allow for multiple files.
