Attribute selectors incorrectly scoped

[ssorallen]

Attribute selectors get incorrect style scoping applied. Consider this example from <core-drawer-panel>:

Source:

core-drawer-panel > core-selector:not(.narrow-layout) [core-drawer-toggle]

Transformed:

core-drawer-panel[style-scope=core-drawer-panel] > core-selector[style-scope=core-drawer-panel]:not(.narrow-layout) [core-drawer-toggle][style-scope=core-drawer-panel]

The [style-scope=core-drawer-panel] at the end is incorrect. It was intended to select any descendant element with the core-drawer-toggle attribute, but they will never have style scopes applied.

A simple attribute selector also becomes scoped:

Source:

[core-drawer-toggle]

Transformed:

[core-drawer-toggle][style-scope=core-drawer-panel]

Never mind. I misunderstood how ::content works now.
