v0.6.2

[0.6.2] — 2026-07-03

Fixes a real bug in the v0.6.1 threshold color-palette popover, reported
with a screenshot right after v0.6.1 shipped: the popover opened hundreds
of pixels off to the side, half off-screen.

Fixed

• The threshold color-palette popover opened far off to the side (or was
  invisible entirely) when used inside HA's real card-edit dialog. Root
  cause was two-fold, and only reproducible inside the real dialog —
  palette_check.mjs's standalone-mounted panel (no <dialog> ancestor)
  never exercised either path:
  1. HA's dialog nests a native <dialog> two shadow roots deep
     (ha-dialog → wa-dialog → <dialog>), and that <dialog> carries
     transform: matrix(1,0,0,1,0,0) — an identity matrix with no visible
     effect, but per the CSS spec any transform value other than none
     still establishes a new containing block for position: fixed
     descendants. The popover's top/left (computed from viewport-relative
     coordinates) were being applied relative to that dialog's own top-left
     corner instead of the viewport, and clipped by its overflow: hidden.
  2. The dialog is shown via showModal(), promoting it to the browser's
     "top layer" — nothing outside it can paint above it regardless of
     z-index, so naively fixing #1 by rendering the popover into a portal
     on document.body made it correctly positioned but fully invisible,
     hidden behind the modal.
     Fixed by rendering the popover into a portal appended as a child of the
     nearest open modal <dialog> ancestor when one exists (found by walking
     the flattened DOM tree — piercing shadow hosts and <slot> assignments,
     not just parentElement) — keeping it in the top layer — with position
     computed relative to that dialog's own rect instead of the viewport's,
     since the dialog is now deliberately its containing block. Falls back to
     document.body with viewport-relative positioning when there's no dialog
     ancestor (e.g. used standalone, as in palette_check.mjs). Verified
     against a live HA instance across six viewport sizes (1920×1080 down to
     800×600) and with a new permanent regression check that opens the real
     dialog and confirms the popover isn't just present in the DOM but
     genuinely clickable at its rendered position, piercing shadow roots via
     nested elementFromPoint calls
     (tools/sandbox/harness/dialog_popover_check.mjs).
