Since updating Home Assistant to 2026.8, the card no longer renders. It only shows the red error box Label must have y property.
The browser console logs the same message once per predefined_selections entry — I have 11 rooms defined and the error appears exactly 11 times. So it is not a single malformed entry: every label is rejected.
The card worked fine with the exact same configuration before the Home Assistant update. The card itself was not updated (v2.4.1, installed ~2 months ago, still the latest release).
Configuration
Every one of my 11 selections follows the documented format and has text, x and y. Example:

What I tried
| Attempt | Result |
|---|
| Hard reload / cache clear | error persists |
Remove offset_y, keep text / x / y | error persists |
Remove the whole label: block from all 11 selections | ✅ card renders normally, zones and room selection work |
So the trigger is the presence of a label object, not one of its properties. offset_y is not the cause.
Console output
XIAOMI-VACUUM-MAP-CARD Version v2.4.1
(11) Label must have y property xiaomi-vacuum-map-card.js:1225
Workaround
Removing all label: blocks restores the card. Room names are no longer drawn on the map, but zone selection and cleaning still work.
