To fix this, we'd need to add support for the TIFF format.

Probably related, the logo of the Romanian fiscal authority (ANAF) is displayed as a broken image when opening the latest versions of fiscal forms in Firefox Nightly (tested with both 92.01a and 93.01a).

THis PDF also shows lack of an arrow-like image; A very similar issue is also seen in a ghostscript PDF and canadian forms.
