something in this patch leads to new warnings:

./ffmpeg -i fate-suite/exif/image_small.webp -vcodec copy -bitexact  file-4087B.webp
./ffmpeg -i file-4087B.webp -f null -

after this patchset

./ffmpeg -i fate-suite/exif/image_small.webp -vcodec copy -bitexact  file-4087B.webp
./ffmpeg -i file-4087B.webp -f null -
[webp @ 0x55a5284bcb80] EXIF chunk present, but Exif bit not set in the VP8X header

something similar happens with "ALPHA chunk present, but alpha bit not set in the VP8X header"
with ticket 4087/5_webp_a.webp

thx
