Description

The absolute-time <DatePicker> inside dropdown-filter-chip.svelte passed label="" with labelHidden, producing an empty <label for="datepicker"></label> at runtime. The input had no accessible name, violating WCAG 2.4.6 (Headings and Labels) and 4.1.2 (Name, Role, Value).

Fix: replace label="" with label={translate('common.start')}. The labelHidden prop stays, so the visual layout is unchanged — the label is rendered to the DOM but hidden from sighted users via CSS. translate and common.start are already present in this file (used on the sibling DatePickers in the isTimeRange === true branch).

Changed file: src/lib/components/search-attribute-filter/dropdown-filter-chip.svelte — one line.

Screenshots

No visual change — label remains visually hidden via labelHidden.

Design

No design changes. Consistent with the two sibling <DatePicker> instances on lines 378–384 and 394–400 of the same file that already pass label={translate('common.start')} / label={translate('common.end')}.

Testing

  • Navigate to a workflows list, open a datetime search-attribute filter chip, switch to "Absolute" time mode.
  • Inspect DOM: confirm <label for="datepicker"> contains "Start", not empty.
  • Screen reader (VoiceOver/NVDA): focus the DatePicker input — announces "Start, date picker" (or equivalent).
  • axe-core: no "Form elements must have labels" / "Element has no name" violations on the DatePicker input.
  • Visual regression: DatePicker layout unchanged; label remains visually hidden.
  • Sibling DatePickers (start/end in range mode) unaffected.

Checklist

  • No new i18n keys needed — reuses existing common.start
  • No visual change — labelHidden unchanged
  • pnpm lint and pnpm check pass

Docs

No documentation changes required.

…start')

The absolute-time DatePicker in dropdown-filter-chip passed label=""
which renders an empty <label> element, leaving the input with no
accessible name (WCAG 2.4.6 / 4.1.2 violation). Replacing with
translate('common.start') + labelHidden gives a screen-reader-visible
label while keeping the visual layout unchanged.
