[Fixed] "Save for web" does not preserve resolution info (PPI aka DPI in case of scan/print image)

[porg]

Tested in GC 12.0.4 (6160):

Scenarios from 2b now both worked

2) Save for web:

b) As WEBP + Embed Exif ON + Reduce to 72 PPI OFF + (Lossless || Quality 80) + (Sharpen None || Sharpen 20%)
→ All results in WEBP with the original PPI preserved which was 144 PPI.

Changing title to [Fixed].
