HP-15C CE woes: 1 bug, 2 limitations, 3 questions

If eg in DEC-mode, you can press 'f' then HEX to temporarily see the value in Hex-mode.
On the original the value is shown as long as the key is pressed, but the 16CE only shows the value for some seconds, independent on how long you press the key.

In the 16C microcode, the f SHOW <base> microcode at ROM address 0f49 calls a subroutine at 00b6 that is supposed to wait for key release. This subroutine is also used for f MEM, f STATUS, SST, and BST. Do those functions continue showing their display as long as the key is held?
