Describe the new behavior?
Created a new Spinner component to replace the native spinner in
<input type="number" />
elements. The native version is misaligned with the Text Field component and inconsistent between browsers.Additional information
This is currently intended only for use within the library. Because input fields already expose controls for accessibility the Spinner component is essentially hidden from the accessibility tree and keyboard interaction.
The major hurdle in adding this to the Text Field component is going to be hiding the native spinner. This can be done by targeting
input[type="number"]::-webkit-inner-spin-button
(or using-moz-appearance: textfield
in Firefox) but because this involves a pseudo-element it doesn't seems to be feasible from the shadow DOM.
