Setting "always" while opening .cfg files in text editor doesn't work.

[b2sql]

When trying to open .cfg files in getting prompt which app to use. When choosing material files text editor as "always" option it doesn't save and I'm getting prompt every time I'm trying to open the file. It only happens with .cfg extension files.

I have the same problem with pdf files. When I want to open a pdf, I select my pdf viewer app to open it. At this moment, Material Files is selected by default with the "Just once" and "Always" options.
After, when I want to reopen a pdf, my pdf viewer app isn't shown with this options "Just one" and "Always". It's still Material Files
I can't reproduce this bug with jpeg files, xlsx or jpg for example, it works well as expected with these files.

I think the bug was not there before the last version (1.7.2)
