Applying an uncommitted function signature in VT replaces the destination with `void func(void)`

[axd1x8a]

Describe the bug
When you apply an uncommitted function signature in version tracking, the destination will be replaced with `void func(void)

Expected behavior
The destination function still gets uncommitted signature

Screenshots

Here is an uncommitted source function signature:

Environment:

• Ghidra Version: 11.4.1
• Ghidra Origin: github

I saw the message about signature in the listing, this is how it looks

@feeeek It looks like it is using the listing's signature, not the decompiler's one but it is odd that it still uses void for the return type given that both the source and destination have undefined return types. Could it be that your apply settings are preventing the signature from being applied correctly? What are your apply settings for the function signature data types set at for the params and the return?

Assuming this is the intended behavior, how can I commit all function signatures with a script without decompiling them all to get the "HighFunction"?
