derive width and height from feature property

[andrewharvey]

The accessible elements currently have a fixed width and height given in the plugin options. It would be nice to set from an expression evaluated per feature.

For example if you had a circle layer with variable circle-radius you could ensure the accessible element had the same width/height as the circle, so the focus style would match what's on the screen.

That's for the source geometry only, it doesn't take into account the paint/layout properties on the layer which create a rendered feature which has a different box to the source geometry.
