| While <div> and <span> aren’t defined as “checkable for the purposes of this |
| feature”, this has no effect on the attribute’s state. |
| |
| We wrap the <span> elements under test with <div> elements so the checking |
| enabled algorithm stops at step 4 (ancestor content attribute), before steps |
| relying on user-agent-defined behavior (see [#concept-spellcheck-default]). |
