I'll try to work on those open points for WC support

refs issue: #1114

Blockly.setParentContainer could be used for setting the Parent for Blockly, but this works only once, and with webcomponents you could have multiple blockly components on the page.
So the parentContainer needs to be stored per workspace

But the tooltip could also be shown outside of shadow dom (wich maybe often is also preferable cause of maybe cliping of the tooltip inside the shadowroot), but at first, the position calculation needs to be fixed

Question:

I'd like to work on official webcomponent support. But there will be refactorings needed, cause you could have multiple blockly instance with different containers for example for tooltips, ....)

Is this something wich will be accepted later? What are the opinions about this?

Maybe look at my draft with already some changes : #7718

Hello! I'm going to close this in favor of #1114

Will repost your question on the other thread.
