Photoshop 2020 strips XMP:RawFileName tag when saving
When a TIF or raw file (eg Canon CR2) that contains the Xmp:RawFileName tag is opened in Photoshop 2020 and then saved (as a jpg or tif), the RawFileName tag is removed.
Issue occurs both when opening the input file via Camera Raw or directly in PS using Open As (TIF only of course), so this doesn't appear to be an issue with Camera Raw not passing the tag to PS.
Tag is saved correctly in Photoshop 2019 versions. All other tags (including Xmp) appear to be saved correctly (consistently with PS 2019).
