Support some way to protect in parsing time reactive tags to be rerendered. #17
Description
If inside a reactive tag one non-HTML-element tag gets re-rendered, all the tag gets rerendered.
It may be problematic for some other HTML elements.
We need some way to protect those elements, by this means:
- Put some decoration in the template on this element for protection.
- Raise an exception in the template parsing time if some reactive part of the template code in the same reactive context can possibly make a protected element be rerendered.
