Hi, I was attempting to demonstrate the case-insensitivity of 18 char ID to my peers and I can't seem to get it to work. 

I ran this soql query:

select id from account where ID = '0013000000Hk05sAAB'

which successfully reports 1 record. 

When I try the all lowercase version 

select id from account where id = '0013000000hk05saab'

It reports 0 records. 

Is this a bug? A limitation of SOQL? Did I misunderstand the case-insensitive nature of 18 char id? I'm confused why the 2nd one pulls up 0 records.
