Two the same page in the stack (two the same id)

[anton_klochko]

Hi all ! Could anyone suggest please, why sometimes we can see two the same page in the stack ? How to get rid of it ? It is generates bugs in code … For example I can see two …

<div id="MyContainer">

Not a whole lot of information to go off of here.
How are you seeing this?
How could I replicate this?
