[11.0.5] Altering slides when using virtual and loop mode is not updating the displayed slides

[joseph118]

Description

When using the core slider with the Virtual and Autoplay module, along with loop mode, initially it loads fine however it breaks after altering the slides using virtual methods.

Opening in Q&A to confirm it is an actual bug and not due to configuration, as I have a similar case in my application with the same issues shown in the demo.

Expected behaviour

When altering the virtual slides, items removed from the collection should remove any item visible on screen. It should also not break the slider.

Actual behaviour

• removing the first slide from the virtual slides does not remove it from the virtual view
• removing couple of slides breaks the slider (e.g. showing empty slides or repeating items on navigation change)
• index 1 is repeated on autoplay/navigation
