Comment (by praem90):

 As per the
 [https://developer.wordpress.org/reference/functions/wp_exif_frac2dec/#source],
 it looks like the function would return the same string if there is no
 slash (/) or the denominator is empty.

 The given string may not be casted into int.

 And the documentation needs to updated.

 Replying to [comment:2 stevegs]:
 > The strange thing about this is only **some** EXIF files cause the
 problem, but it seems no JFIF file does so.
 >
 > I've generally found PHP8 is a lot more strict (especially regarding
 typedefs or unexpected nulls) than its predecessor, having found many
 similar errors in some plugins (resolved by updating, re-writing or
 deleting).  Hope this has been helpful.
