Description
Repro steps:
- Open
quick forest swims softly - Go to 0x14000107c
- Right click -> Override call Type
- Type in
void calltarget(uint64_t num @ rax), and press OK - Observe the HLIL does not change
I am not sure whether this is related to #5583 and/or https://github.com/Vector35/binaryninja-api/issues/6458
P.S.: this does not look like a regression to me, tested a few earlier versions and they all behave in the same way

Research direction
Reproduce the issue by opening quick forest swims softly, navigating to 0x14000107c, and using Override call Type with the provided signature. Inspect why the HLIL does not change and compare the behavior with issues #5583 and #6458. Done means the overridden system call type is reflected in the HLIL.
