Hi @wilson-xu-sap

I wasn't able to reproduce this error. Could you please add an isolated example, preferably by using this StackBlitz template. Please also include the version of the browser and the OS where this error is occurring in.

Hi @Lukas742 This is not easy to reproduce, as I mention in the content, you need to click the button randomly and repetitively. Sometimes it fails at first time, sometimes it never fails.
You can check the recording I have provided, it is not reproducible until I click it three times.

macos version: 15.4.1
chrome version: 136.0.7103.114

@wilson-xu-sap I clicked multiple times, with different intervals, but no error is thrown for me. (Tested in Chrome and Safari)

Edit: I got it. When clicking close to the border of the button, the error is thrown.

@wilson-xu-sap I'll forward this issue to the ui5-webcomponents repo, as the component is developed there.

Hi Colleagues,

when clicking close to the border of the button that is rendered if a custom header is used, an error is thrown. The issue can be observed in your playground example:

It seems that a CustomEvent is expected there, but the native PointerEvent is called.

@Lukas742 Thanks for your carefulness and patience!

Hello @SAP/ui5-webcomponents-topic-b,

Could you please take a look at that issue?

I think it's related to change introduced with: #11318

The issue is reproducible when the click occurs over the border of the component.

Regards,
Nayden
