…certinia#863) Windows fractional display scaling (125/150/175%) makes getBoundingClientRect().width non-integer; passing it to MinimapDensityQuery as a bucket count threw "Invalid array length" and aborted timeline init before interaction handlers attached, so zoom/pan/keys all appeared dead. Floor the count at the single query() entry point. Bump 1.20.1.
