Answer from F5 support:

 

Product Development has identified this issue (bug ID570973) as the cause. ID570973 is fixed in 12.0.0 HF3 and 12.1.0. Both host and guest need to running a patched version. ID570973 is also going to be fixed in an upcoming hotfix release in the 11.6.1 code branch. At this time there is no information as to the specific HF that it will be fixed in. You may search askf5.com for '570973' to see when and where it is fixed, when it is fixed.

 

Currently this is the only page it is documented on: https://support.f5.com/kb/en-us/products/big-ip_ltm/releasenotes/related/relnote-supplement-hotfix-bigip-12-0-0.html
