QQC2 SplitView does not honor size constraints when parent is resizing

It looks like QQuickSplitView does not respect size constraints (min/max/fill width/height) when the parent item is resized.

Here is an example:

import QtQuick
import QtQuick.Window
import QtQuick.Controls
import QtQuick.Controls.Material

ApplicationWindow {
    width: 640
    height: 480
    minimumWidth: 400
    minimumHeight: 400
    visible: true
    title: qsTr("Hello World")

    SplitView {
        id: splitView

        anchors.fill: parent
        hoverEnabled: true

        Pane {
            Material.background: Material.Blue
            SplitView.minimumWidth: 50
        }

        Pane {
            Material.background: Material.Green
            SplitView.fillWidth: true
            SplitView.minimumWidth: 300
        }

        Pane {
            Material.background: Material.Blue
            SplitView.minimumWidth: 50
        }
    }
}

1. Resize first item so that it uses the maximum space available (see screenshot Step 1 -> Step 2). The minimum width of all items is respected at this point.
2. Decrease the size of the window (see screenshot Step3 & Step4) -> note how the first item still occupies the same space and how the rest of the items are cut. Since both the right and the central item have a minimumWidth set and there is still enough space available for all items to be visible, I would have expected the blue item to be "pushed" to ensure all items are still visible and respect their minimum width.
3. Weirdly, if you click on the first split handle and move it very slightly then the item layout is magically restored and all items can be seen (see screenshot Step 5 & Step 6)
