Maybe i understand it wrong, but...

When i put code like:

<div t-esc="'test'"/>

...into embedded code block in website, whole page goes to bad state...

No more blocks can be added and only thing possible is editing existing ones...

I figured out, that when i put this small piece of code outside tag, where is defined class="oe_structure", it works perfectly (page remains in correct state)...

Is this bug or this behaviour is correct?
