Steps to reproduce

1. Add a new document, for example an image.
2. Add a new widget page (p.e. 'nested').
3. From widgets selector, add 'Nested Applications' to the page.
4. Drag two asset publishers inside 'Nested Applications'.

Following behavior can be gotten with signed and unsigned user when page 'nested' is browsed.

Observed behavior

• When HTML source is examined, there are two '<div>' elements with attribute 'role="main".

Expected behavior

• There must be only one '<div>' element with attribute 'role="main" because product's FTLs do not use 'aria-labelledby' attribute.
