As indicated in Npcap issue #171, it appears that, in at least some circumstances, the Windows networking stack may strip out VLAN tags, and might put them in some metadata attached to the packet, so that Npcap could extract the VLAN tag from the metadata and insert it back in the raw packet data.
Unfortunately, Npcap currently doesn't do that, which means that, if that's what's happening, Wireshark never even sees the tag, and there's nothing it can do to get at the tag information, so the tags are permanently lost in a capture - Wireshark can't display those VLAN tags because it doesn't have them.
