Button in fragment misses a __FRAGMENT__ replacement on rerender

[kevindeyne]

In version 0.9.0, when you have a fragment which contains a button, upon rerender it can revert back to __FRAGMENT__

<button class="slot" onclick="_M.doAction(event, '__FRAGMENT__', `doAction(0)`)">Standard damage</button>

instead of

<button class="slot" onclick="_M.doAction(event, 'combat', `doAction(0)`)">Standard damage</button>

I'd need to investigate what specifically causes this

Core of this problem lies in hitting the max depth:

medusa/medusa-ui/src/main/java/io/getmedusa/medusa/core/render/Renderer.java

Lines 233 to 238 in c5f6c7e

	public Flux<DataBuffer> renderFragment(String html, Session session) {
	session.setDepth(session.getDepth() + 1);
	if(session.getDepth() > 100) {
	return Flux.just(FluxUtils.stringToDataBuffer(html));
	}
	return loadFragments(html, session).flatMapMany(parsedHTML -> {

Which hits 100 pretty fast in my example

Figured out this is caused by not resetting the session depth after rendering. Session resets per page load, but if a page is continuously used, it keeps counting up.
