Close the current modal page before showing another one!`\r\n\r\nI am not sure if this is the expected behaviour, so I need to know what I am doing wrong. Please note, that in our real app there are some conditions for showing the modal pages, so it might be possible to skip one of the modal pages or even all of them.\r\n\r\n\r\n\r\n### Please provide the following version numbers that your issue occurs with:\r\n- CLI: 4.0.0\r\n- Cross-platform modules: next (4.0.0-2018-04-25-02)\r\n- Runtime(s): 4.0.2\r\n\r\n### Please tell us how to recreate the issue in as much detail as possible.\r\n1. Start the app\r\n2. Tap the button to open the first modal\r\n3. tap the button to close this modal, so the second modal should be opened, but this does not happen on iOS.\r\n\r\n### Is there code involved? If so, please share the minimal amount of code needed to recreate the problem.\r\n[NSIssues4.zip](https://github.com/NativeScript/NativeScript/files/1947861/NSIssues4.zip)\r\n\r\n","author":{"url":"https://github.com/felixkrautschuk","@type":"Person","name":"felixkrautschuk"},"datePublished":"2018-04-25T16:10:02.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/5744/NativeScript/issues/5744"}
