Issue Description

On iOS, I have an ImageSource that I want to pass to some Image components:

<Image *ngIf="cond" [src]="myImageSource"></Image>
<Image *ngIf="otherCond" [src]="myImageSource"></Image>

But when Image is disposed, it clears the content of the provided ImageSource (this.imageSource.ios = null; ), which makes it not reusable!

NativeScript/packages/core/ui/image/index.ios.ts

Lines 29 to 41 in 0506012

public disposeImageSource() {
if (this.nativeViewProtected?.image === this.imageSource?.ios) {
this.nativeViewProtected.image = null;
}
if (this.imageSource?.ios) {
this.imageSource.ios = null;
}
this.imageSource = null;
queueGC();
}

Note that when src is an ImageSource, the _createImageSourceFromSrc function does not create but just use the provided ImageSource

NativeScript/packages/core/ui/image/image-common.ts

Lines 124 to 127 in 0506012

} else if (value instanceof ImageSource) {
// Support binding the imageSource trough the src property
this.imageSource = value;
this.isLoading = false;
