Editing web demo's DragValue with keyboard resets tab cursor position

1. Navigate to https://emilk.github.io/egui/#demo
2. Using keyboard only (Tab key), navigate to "DragValue:" element.
3. Press Enter, type some other number, accept with Enter.
4. Press Tab again, intending to go, for example, to "Color picker".

Expected:

Color picker element (or at least its label) gets highlighted, as it is next after DragValue.

Actual:

It resets active element to the very beginning, requiring much more Tab presses to get back to DragValue, then to the color picker.
