Description

A pane that has Closeable="false" set does not render a "close" button and should not be closeable through any user interaction. However, pressing the Esc keyboard key (while the pane is floating and has the focus) closes the pane.

Steps To Reproduce

Run the following REPL example: https://blazorrepl.telerik.com/QTkgmKuM23c0uPv125

1. Focus the floating pane.
2. Press the Esc keyboard key.

A slightly different scenario: there are no panes declared in a DockManagerFloatingPanes tag. The user drags a DockManagerContentPane making it float, then presses Esc key: https://blazorrepl.telerik.com/QJuUGUlv43toAJhk40

Actual Behavior

The floating pane closes.

Expected Behavior

The floating pane remains open.

Workaround:
Add the following script to the view:

<script suppress-error="BL9992">
    document.addEventListener(
      "keydown",
      function (e) {
        if (e.key === "Escape" && e.target.classList.contains("k-dock-manager-window")) {
          e.stopImmediatePropagation();
          e.preventDefault();
        }
      },
      true
    );
</script>

No response

When a content pane is dragged and docked into an empty DockManager, the pane disappears instead of being displayed within the layout.

Example: https://blazorrepl.telerik.com/mJETQguc51eI2QhV23

I am trying to change the orientation of the SplitPane after the DockManager has rendered but nothing changes. It seems like the parameter is not reactive.

ADMIN EDIT

A possible option for the time being is to dispose and reinitialize the DockManager when you want to change the SplitPane Orientation. 

Here is a runnable sample: https://blazorrepl.telerik.com/QfYHboFl280vuIkL03.

I am using the DockManager with DockManagerTabGroupPane. One of the tabs contains a TelerikSplitter. When I now try to dock a FloatingPane next to, it always tries to dock onto the TelerikSplitter instead of the DockManagerTabGroupPane.

This only happens, when the area of the SplitterPane overlaps with the docking symbols (Dock Navigator).
