fix: prevent error overlay style being overridden (fixes #9969) #9971



Copy link

@sapphi-red sapphi-red commented Sep 3, 2022


Currently, error overlay uses :host to declare styles for the root element.

:host {
position: fixed;

But when a style is declared for that element like *.
It gets overridden by that.

Outside styles always win over styles defined in shadow DOM.

For #9969, position: fixed was overridden with position: relative.

fixes #9969

Another way is to set { state: 'attached' } but that still might break ecosystem tests that relies on this.
