Rendering a custom element inside a strictly private component renders it twice in componentOpen event

[bob2517]

This is only an issue in the component event "componentOpen" and works as expected everywhere else.

It works fine if you specify the component by reference, like render: "{|myTag}".

But it just draws it twice when you do render: "\";

It looks like it's related to the sequence with which components get rendered. Custom elements render automatically in a separate place in the core to the main component render, which is where I suspect the problem lies. It would explain the double render, because the same render code would get called twice.

It's a niche bug, but it needs to get fixed as it may show up any other flaws, so I'm doing this one now.

Back on this. Focus!
