Hi,

After updating to the 2026.2.519 version, the icons for the date and time pickers are shifted a few pixels down. When clicked, a black rectangle appears around them, which, as you can see, it is truncated at the bottom. This is using the Bootstrap skin.

I'm getting the below error when focusing out of the "RadDateTimePicker" with the following configuration.

Code in the aspx page:

<telerik:RadDateTimePicker runat="server" ID="TlrkDateTimeEdit"
DateInput-DateFormat="g" DateInput-DisplayDateFormat="g"
DatePopupButton-Visible="false" TimePopupButton-Visible="false"
PopupDirection="BottomLeft" ShowPopupOnFocus="true">
</telerik:RadDateTimePicker>

Script error in browser console:
"Cannot read properties of null (reading 'focus')    at Telerik.Web.UI.Calendar.Popup._raiseClosed"

In version R3 2019 (2019.3.917), the following issue is observed with various date pickers: 

Reproduction code and steps:

<telerik:RadDateTimePicker RenderMode="Lightweight" ID="RadDateTimePicker1"  runat="server" >
</telerik:RadDateTimePicker>

1) open date picker, 
2) click on the month/year to open the MonthYearFastNavigation
3) Click Ok or Cancel

Expected: date selected
Actual: JavaScript error: Uncaught TypeError: Cannot read property '_popupButton' of null
