Daily Accessibility Reviewaria-sort attribute uses localised/capitalised string instead of required ARIA token value

Problem

The ariaSort() method in SortableTable/THead.vue returns localised strings for the aria-sort attribute. The ARIA specification requires aria-sort to use one of four fixed token values — all lowercase English — regardless of the page's display language.

File: shell/components/SortableTable/THead.vue (lines 166–172)

ariaSort(col) {
  if (this.isCurrent(col)) {
    return this.descending
      ? this.t('generic.descending')   // → "descending"  ✔  (but varies by locale)
      : this.t('generic.ascending');   // → "ascending"   ✔  (but varies by locale)
  }
  return this.t('generic.none');       // → "None"  ✗  (capital N; must be "none")
},

The English en-us translation for generic.none is "None" (capitalised). aria-sort="None" is not a valid ARIA token and will be treated as an invalid value by browsers and screen readers — they may fall back to aria-sort="none" or ignore the attribute entirely.

For non-English locales the translated strings will differ further (e.g. German "Aufsteigend", French "Croissant"), which always breaks the attribute since aria-sort values are not translated.

Recommended fix

Replace the i18n calls with the fixed ARIA token strings:

ariaSort(col) {
  if (this.isCurrent(col)) {
    return this.descending ? 'descending' : 'ascending';
  }
  return 'none';
},

The visual label for the sort direction (if any is needed for display purposes) can remain translated; only the aria-sort attribute value must use the fixed tokens.
