The canvas reparents 1.12's `WorldMapButton` into the zooming child so that every
1.12 addon's icons pan and scale with the map. `WorldMapFrameAreaFrame` hangs off
that button in the client's own XML — it covers the art, so that is where the
label that names what the cursor is over was hung — and it went along with it.
Its label is a 102 px THICKOUTLINE FontString. Inside the canvas it scales with
the zoom, so at zoom 2.5 every letter is a 261 px glyph, and one zone name's worth
of those is most of the 2048² glyph sheet. Measured in grom's 2026-11-02 session:
one `ui_text: a 261.10907 logical-px request … past the 256 ceiling`, then 20
`glyph sheet full … resetting at the frame boundary`, one per hover, each of them
a frame in which every string on screen is missing — the map "flashing the
interface". Frame cost with the map open went 11 ms → 16-20 ms over the same
window.
So it goes back on the window, anchored to the container's top, which is where the
art's top edge is now; at rest that is the pixel it was already at. Measured
through the harness: the biggest text under `WorldMapFrame` was 102 px at zoom 1
and 1632 px at zoom 16, and is now 102 px at every zoom.
