Equals sign followed by question mark writes cypher 5 under specific conditions

[GitHubinatrix]

If I try to write
#5 =?
what I get is
#5 =5

This was happening in portable version (x64) 6.23.712.1 rc and is still happening in portable (x64) 6.24.1221.1 on Windows 10 Enterprise 20H2 x64 [10.0.19042]

In Menu Settings, uncheck "Calculate Tiny-Expressions"

This checks out. Thank you for pointing me out to this

So it is not a bug but a selectable feature I did not knew about. Although I would like to point out that
5!+5=
does not result with
125
but with
0
as apparently the sign for factorial is not recognized as such and thus calculated [or recalled from some table] - while the hashtag sign does not break the equation i.e.
#5+5=10

Take a look at this issue for more explanation: #2775 and #2775 (comment)
