Steps to reproduce

Output Japanese hiragana and katakana using any CUI software.

Hiragana test string : *かきくけこ*がぎぐげご*さしすせそ*ざじずぜぞ*たちつてと*だぢづでど*はひふへほ*ばびぶべぼ*ぱぴぷぺぽ*
In JSON : "*\u304b\u304d\u304f\u3051\u3053*\u304c\u304e\u3050\u3052\u3054*\u3055\u3057\u3059\u305b\u305d*\u3056\u3058\u305a\u305c\u305e*\u305f\u3061\u3064\u3066\u3068*\u3060\u3062\u3065\u3067\u3069*\u306f\u3072\u3075\u3078\u307b*\u3070\u3073\u3076\u3079\u307c*\u3071\u3074\u3077\u307a\u307d*"

Katakana test string : *カキクケコ*ガギグゲゴ*サシスセソ*ザジズゼゾ*タチツテト*ダヂヅデド*ハヒフヘホ*バビブベボ*パピプペポ*
In JSON : "*\u30ab\u30ad\u30af\u30b1\u30b3*\u30ac\u30ae\u30b0\u30b2\u30b4*\u30b5\u30b7\u30b9\u30bb\u30bd*\u30b6\u30b8\u30ba\u30bc\u30be*\u30bf\u30c1\u30c4\u30c6\u30c8*\u30c0\u30c2\u30c5\u30c7\u30c9*\u30cf\u30d2\u30d5\u30d8\u30db*\u30d0\u30d3\u30d6\u30d9\u30dc*\u30d1\u30d4\u30d7\u30da\u30dd*"

(Note those test strings do not include all kanas, but only those that have common (han)dakuten variants)

Expected Behavior

These characters should render as double cells (except the separating *s), with their glyphs centered.

See the result in gnome-terminal:

Actual Behavior

Instead, all characters are left-aligned in their cells, and several (han)dakuten, but not all, are sized smaller than two cells, but still wider than a single cell... they look more like 1.5 cells but the length of the run of characters still accounts for double cells.

Here is the result of the same output in Windows Terminal 1.16.2642.0 using Atlas Engine

These are precomposed characters, their decomposed versions make the wrong spacing even more extreme.

Note that this is a bug introduced by the Atlas Engine, as in the same version of Windows Terminal but with Atlas Engine disabled, the result looks fine:
