v0.5.4

Patch Changes

• 3866289 #442 Thanks @geoffrich! - Correctly determine accessible name when element contains a slot.

  Previously, computing the accessible name would only examine child nodes. However, content placed in a slot is is an assigned node, not a child node.

  If you have a custom element custom-button with a slot:

  <button><slot></slot></button>
  
  <!-- accname of inner <button> is 'Custom name' (previously '') -->
  <custom-button>Custom name</custom-button>

  If you have a custom element custom-button-default with default content in the slot:

  <button><slot>Default name</slot></button>
  
  <!-- accname of inner <button> is 'Custom name' (previously 'Default name') -->
  <custom-button-default>Custom name</custom-button-default>
  
  <!-- accname of inner <button> is 'Default name' (previously 'Default name') -->
  <custom-button-default></custom-button-default>

  This is not currently defined in the accname spec but reflects current browser behavior.
