CSS Styled Content: file references not working with image compression
When using image compression with CSS styled content
all existing data in the $imgConf array is emptied.
If using a sys_file_reference, the file object
for resolving the file data does not consider
the option "treatIdAsReference" anymore as
it is unset as well.
How to reproduce: Add a file with image compression
and the wrong image is rendered, as the file UID is used
not the file reference UID.
If you have a sys_file UID 23, and a sys_file_reference ID 45
then the sys_file 45 is displayed instead of sys_file 23.
