The capture stops because the Linux capture mechanism, i.e. the PF_PACKET
socket bound to the interface, delivers an ENETDOWN error.

If only one ENETDOWN error is delivered, libpcap can be changed to ignore it,
in which case this is a libpcap bug, not a Wireshark bug.

If, however, it continues to deliver ENETDOWN errors, and refuses to supply
packets, this is a Linux kernel bug.

In either case, this isn't a Wireshark bug, unless you can get different
behavior from some other application using libpcap to capture traffic.
