No, as Smart says, each device yoke counts as two conductors and they are given the cubic inch value of the largest gauge connected to the device on the yoke, in your case 2.25 cubic inches time two for a total of 4.5 cubic inches per the receptacle device yoke.
There is no exception in a pancake box that allows us to ignore the volume of the EGC if it is a wire brought into the box by the wiring method. You might be thinking of grounded wiring method like metallic raceway or something like AC cable or MC-AP cable where the EGC is the cable or raceway, and a wire-type bond between the luminaire and the grounded pancake box begins and ends inside the box. . . that little bond wire we are allowed to ignore. But if the wiring method is NM-B, say, then the EGC has to be given a cubic inch volume.
It's not pretty, but you can place a Wiremold box extension over the existing 1" deep box to increase the overall box volume.
works for me. A 2-wire circuit cannot be a mwbc.
this one?

some here once called it the pregnant box.
yep, have plenty of width.
The title of 250.148 is "Continuity and Attachment of Equipment Grounding Conductors to Boxes."You aren't imagining anything-
250.148(B) says device removal cannot interrupt EGC continuity.
If someone was using the scr for feed thru they could split and remove a portion of the nm jacket for a couple of inches or so, exposing the wires, then strip off enough insulation off the H&N to loop around the conductor, loop egc- you would loop all of the wires and continuity would be maintained. Or if there is enough room, egc continuity can also be maintained by doing a Y splice and using a buchanan- egc excess protruding from end of splice cap would wrap around egc terminal.
