What browsers are you seeing the problem in?

Firefox, Chrome, Safari, Microsoft Edge

How can we reproduce this issue?

1. Go to https://opensource.adobe.com/spectrum-web-components/components/slider/
2. Navigate using the keyboard
3. Observe there is no tab stop on the handler when the slider is editable

Sample code or abstract reproduction which illustrates the problem

Seems like this was intentional, as per

spectrum-web-components/packages/slider/src/HandleController.ts

Line 557 in bd35e1b

tabindex=${ifDefined(this.host.editable ? -1 : undefined)}

Severity

None

Logs taken while reproducing problem

No response

The intent behind this was to reduce the number of tab stops when interacting with a page - particularly one with lots of sliders as is common on photo editing applications. All of the functionality of the slider can be accomplished by interacting directly with the edit field directly and the slider will echo those changes so the slider was seen as being redundant in this case.

I'm very interested to know if this is something that was reported by a user who couldn't operate the control or if it was something reported by someone performing testing.
