System.Author and System.Keywords windows properties are not added to downloaded images

Bug description

User-specified metadata properties under "Windows Property System" in the settings menu are not saved to downloaded images.

Steps to reproduce

1. Add metadata properties under "Windows Property System" per the screenshot below.
2. Download any tagged image(s) from any arbitrary booru.

Expected behavior
Windows properties to be embedded in downloaded images if specified as per the screenshot below.

Context
I am relying on FileMeta in order to view the metadata of downloaded files. I am only checking PNGs at this point in time, and believe I've selected the correct categories within FileMeta in order to properly view tags.

Windows Properties are not saved even when downloading entirely new images. However, exiftool metadata is saved successfully.

Screenshots

System information

• OS: Windows 10 Version 22H2 (OS Build 19045.4780)
• Grabber version: 7.12.2 (x64)

Hello 👋

My settings:

Saved file:

Seems to be working fine for JPG for me, is the problem on your end only for PNG images? (i.e. those managed by FileMeta)
Are you able to set the author on the file manually through the Windows "properties" window?

The issue only existed for PNG images. JPG worked perfectly and metadata for that file extension was saved.

With FileMeta installed, I was able to manually add metadata to PNG images. Since I was able to manually add the metadata, and Grabber wasn't adding it despite my settings, I opened this issue.

I have since deleted Grabber and File Meta for personal reasons. Leaving the issue open, but feel free to close it, should you not wish to pursue this potentially vain problem.
