.heic image files not rotated matching metadata

[LysolPionex]

JPG and other image files having a rotation in their metadata are shown correctly in the thumbnail (and preview panel). HEIC image files are shown without their rotation taken into account (though they appear correctly in the preview panel).

please post a sample file

Can I possibly email/DM the sample file? I only have pictures of my kids as examples and don't feel comfortable posting them online. Or I can wait till I come across a non-kid pic. I have a few thousand photos to sift through.
