Adaptive actionsheet closes immediately when clicking the arrow button after a value has been selected

[zstoyanova9]

Description

The ComboBox component with adaptiveMode set to "auto" does not open the adaptive actionsheet when the arrow button is clicked on a mobile screen after a value has already been selected. It seems like the actionsheet opens briefly and immediately closes in this scenario.

On the contrary, clicking on the input field of the ComboBox opens the adaptive actionsheet as expected.

Steps To Reproduce

1. Open the following demo on mobile - https://demos.telerik.com/kendo-angular-ui/demos/dropdowns/combobox/adaptive-mode?theme=default-ocean-blue
2. Open the ComboBox and select a value.
3. Reopen the ComboBox by clicking on the arrow button.

Actual Behavior

After a value has been selected, clicking the arrow button of the ComboBox on mobile causes the adaptive actionsheet to open briefly and then immediately close on its own.

Expected Behavior

Clicking the arrow button of the ComboBox on mobile should open the adaptive actionsheet as expected, regardless of whether a value is already selected.

Hello,
In my case, when no item is selected and I click on the drop down button, actionsheet appears and disappears immediately AND the item that was on the same location as the dropdown button is selected.
I have it when the device is set to an iPhone in Chrome DevTools.
I also have it on a real iPhone device.

I tried the suggested workaround, but does not work in my case.
To get a better overview, I added some logs in your suggested code:

Here is the result :

I am getting a second close event, which is not prevented.
To investigate further, I commented out the following line in onComboClose : this.arrowButtonTapped = false;
Here is what I get :

I assume that in my case, tapping on the button also triggers the "selection" of the item placed at the same level as the button.

Letting the the setTimeout reset the arrowButtonTaped prevents the "second" close event to close the action sheet.
The only drawback is that an item is already selected.
