Submit multiple pull requests if needed. --> ## What is the current behavior? <!-- Please describe the current behavior that you are modifying. --> <!-- Issues are required for both bug fixes and features. --> Issue URL: resolves #24907 `ion-menu` currently clears the `menuInnerEl` and `backdropEl` refs created by Stencil when `disconnectedCallback` is fired. If the `ion-menu` component is re-mounted but _not_ re-rendered, those refs will still be `undefined` when the `open` method is called, resulting in the linked issue. Note that if the `ion-menu` re-renders before `open` is called then this issue does not reproduce. This clearing behavior was added ~6 years ago before we utilized Stencil refs: https://github.com/ionic-team/ionic-framework/blob/687b37ad3e3237b874473817bb7b59143ac113ce/packages/core/src/components/menu/menu.tsx#L136-L137 During this time we had to manually create and clear the element references. Several years later we moved to using Stencil refs, but we did not remove the logic that clears the refs: d83d8ee ## What is the new behavior? <!-- Please describe the behavior or changes that are being added by this PR. --> - Menu no longer sets `menuInnerEl` and `backdropEl` to `undefined` in `disconnectedCallback`. - The `close` method is called so that the state is reset prior to the menu being re-added. I observed that without this, the animation to re-present a menu did not work correctly. ## Does this introduce a breaking change? - [ ] Yes - [x] No <!-- If this introduces a breaking change, please describe the impact and migration path for existing applications below. --> ## Other information <!-- Any other information that is important to this PR such as screenshots of how the component looks before and after the change. -->
