[Enhancement] Use Auto Styler to trigger the appearance of the re-render button

[InsertUser]

As the new Auto Styler causes the map to be rendered based on MapCSS in the Query edit panel I think it would be a bit more consistent if it also caused the re-render button to appear.

The new Auto Styler generates a style based on a key and then rerenders the map according to this style. The new style is then editable in the query code pane but there is no way to apply edits to the new style without re-running a query.

Previously any map display that used a custom MapCSS style displayed the re-render button because a re-run was always required to get the initial MapCSS style to be applied and the re-render symbol (🔃) appears after the query response for queries with an accompanying style.

Having one method of applying a style show the re-render button and the other method not show it is a little confusing (if only briefly).
