Unable to write category data into webp format file

After setting a category in a webp format file and copying it to another directory using windows explorer, the category data is gone.
The same operation jpg is no problem.
XnViewMP version is 1.5.0.

do you write category in embedded metadata?

What is embedded metadata?
Is that mean .xmp file ?
I did't create .xmp files to save metadata.
JPG can write metadata into the JPG file.
I think writing metadata to the file is very cool.
Is that possible to write metadata into WEBP files?

Thank you for your answer, I hope support writing category to webp files ASAP.

Hello, I use webp a lot, and need to use categories metadata. Is there possibly a roadmap to add `write to file` metadata/xmp for WEBP? This would be a boon. Thank you
