Why does the ionDidOpen event of ion-menu trigger when the input input field is dragged on the menu page?

Use environment: Ionic4, Android platform, Angular7

Problem Description: When the text drag selection in the input of the ion-menu area occurs, the external ionDidOpen event will be triggered unexpectedly, resulting in the shrinkage of the menu page drag and triggering the switch event, which will cause the form text in the menu to be unable to be selected by dragging.

Hello,

I have been trying to get ionDidOpen to work but having no luck It looks like you’re having more luck than me,
Could you please share an example?
