material 3.0.3

Fixed

• A selected toggle icon button inside a toolbar keeps its round shape.
  A standalone toggle morphs round to square when selected (icon buttons specs),
  and toolbar items inherited that morph, so the selected Bold of a formatting
  toolbar turned a rounded square — a shape the toolbars specs warn against in
  the floating container. Selection inside a toolbar is shown by colour roles
  alone (the toolbar token set has no item shape tokens), so the round radius
  now stays in every state. Extending that to the pressed state — and to docked
  as well as floating toolbars — is this library's choice (round stays round),
  not something the specs ask for. The pin is each item's own resting radius,
  on the bar's direct items only, whatever the tag prefix the elements were
  registered under — the toolbar's sheet matches the marker attribute every
  icon-button host of this library carries. The radius is right at first
  paint on the paths the checks cover: elements created in the browser,
  renderElement() output, and the server render of the React, Vue, Svelte
  and Solid adapters, which all write the marker into their markup. Marker-less
  markup still pins under the default m- prefix, where the sheet can spell
  the tag. Standalone toggles, square buttons, the overflow menu's content and
  explicit --mtrl-button-shape-* overrides are unchanged.

• An internal marker attribute, data-mtrl-icon-button, now appears on icon buttons; it carries no public API.
