Material Design Widgets: Input - data point not updated under Android/Google

[desperatePete]

I use the input widget to enter times (hh:mm). Under Android/Chrome, a pop-up with the Google clock appears after clicking on the widget. Here I can enter the time with just two clicks. So far so good...
Unfortunately, the entry is not transferred to the data point, but only displayed in the widget. Only after activating any other widget the data point is updated.
Under Windows/Chrome I can enter the time via keyboard and it is also taken over.
Under RaspianOS/Chromium the widget does not work (this is just for information).

I suspect that the problem is with the widget and would be happy if someone could fix it.
