SUMMARY

When using org.freedesktop.portal.FileChooser.SaveFile with "current_file" the extension is removed.

STEPS TO REPRODUCE
1. Use SaveFile with "current_folder" and "current_name" to save a file with an extension.
2. Use SaveFile with "current_file" to save over the previous file.
3. Notice that it is offering to save without the extension.

OBSERVED RESULT

The dialog resulting from SaveFile with "current_file" set fills the filename field without an extension.

EXPECTED RESULT

Either the filename field should have the extension of the value provided by "current_file" or the filter should automatically select the filter that matches the given extension.

ADDITIONAL INFORMATION

I worked around it by setting the "current_filter" field.
