PDF/A-4 test case 6-2-4-3-t04-pass-e is wrong

[bdoubrov]

Attached PDF uses DeviceRGB and assumes that is redefined to the transparency group color space (CalRGB).

However, that is not the case since the transparency group is a non-isolated group in which case the group color space is inherited.

PDF 2.0:
11.7.2 Colour spaces for transparency groups
“Non-isolated groups shall inherit their colour space from the nearest ancestor isolated parent group (subject to special treatment for the page group, as described in 11.4.7, "Page group")."
