Research direction
Start with the platform-specific CSS guidance linked in the issue and reproduce the behavior using items.component.css, items.component.android.css, items.component.ios.css, and items.component.ts. Investigate why the common stylesheet is resolved to the Android variant, then verify that the shared uppercase rule and each platform-specific color rule are applied together.

Describe the bug
When adding platform specific css then the common.css is not being applied e.g: I have 3 css according to the docs: https://docs.nativescript.org/guide/styling#platform-specific-css
items.component.css
items.component.ios.css
items.component.android.css
When items.component.css is imported into the items.component.android.css then items.component.css rule aren't applied.
To Reproduce
Add 3 css
items.component.css
items.component.ios.css
items.component.android.css
Add styleUrl: 'items.component.css', into items.component.ts
Update items.component.html:
<ActionBar title="My App"> </ActionBar>
<GridLayout rows="*,*">
<Label row="0" text="Test" class="test"></Label>
<ListView row="1" [items]="itemService.items()">
<ng-template let-item="item">
<StackLayout [nsRouterLink]="['/item', item.id]">
<Label [text]="item.name" class="text-lg text-gray-500 p-4"></Label>
</StackLayout>
</ng-template>
</ListView>
</GridLayout>
Update 3 css file each with different rules:
items.component.css
.test {
text-transform: uppercase;
}
items.component.android.css
.test {
color: purple;
}
items.component.ios.css
.test {
color: green;
}
Expected behavior
Expect thar the items.component.css rule be applied for Test word be in Uppercase but only color changes in ios and android correctly.

Additional context
What I noticed is that it prints this in the console: resolving "/home/projects/nativescript-stackblitz-templates-7sgpxgkm/src/app/item/items.component.css" to "/home/projects/nativescript-stackblitz-templates-7sgpxgkm/src/app/item/items.component.android.css"
