No, it is not.

We do not even know if the OP used HTML5.  You are jumping to conclusions 
again, and I am tired of it.

Microsoft does not seem to care about your layman opinion.  They seem to 
care more about backwards compatibility, or they have just neglected to fix 
this for their supposed-to-be HTML5-compliant browser.  Who knows.

That is correct, it is not the main cause *in IE 10*.  But the OP *did* 
*not* *use* *IE* *10*.

So there is another MSHTML inconsistency.  What else is new.  This does not 
mean that you should use such IDs, at least not in HTML 4.01.

No, the main cause was cluelessness.  But there appears to be no means to  
talk sense into you, so I will stop trying and wasting my time with you.
