Use case

SystemContextMenuController.show will hide and show the context menu if targetRect differs by even a fraction of a pixel.

We are building a text field that can be visually stretched by the user (similar to Liquid Glass), and would like control over this behavior, as not every transformation should lead to the system context menu disappearing and appearing again.

We would like to work around this by calling show() only if the menu is not currently being displayed.
However, we don't have any safe way to do that, as we cannot know from the outside whether the menu is currently being shown, since isVisible is marked @visibleForTesting.

Proposal

Make isVisible a public getter, so it's safe to consume and would constitute a breakage if removed at a later point.
