New UX : Source model selector unsable from page to page

Hi

 

Sorry for the repost if somebody already realized this issue.

 

A client implemented to new ALM feature for the standard UX.

 

She realized that the selector can randomely switch form one source to the other while switching the page.

 

Of course it's very dangerous. She is performing some UAT on the DEV and suddently she realize that she erased data on the production environnement.

 

Is it the intented behaviour ?
