Stepping through disassembly can get the Dissambler view out of sync with the "stepping cursor"

See the screenshot. I know that the execution is currently at 0x7f811a8bf904, and the popup over the "??" in the stack view actually tells me that, but there is no visual indication in the Disassembler view. Also, with each further step, the Disassembler view removes the first line and adds a further line to the bottom, but doesn't add a stepping cursor.
