I can confirm that it doesn't work with 5.2.0-050200rc7-generic #201906300430 SMP Sun Jun 30 04:32:31 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux.
Had it work with https://github.com/cilynx/rtl88x2BU_WiFi_linux_v5.3.1_27678.20180430_COEX20180427-5959 in the 4.18 kernel though, though I still haven't made it connect to protected networks.
