+## Input - non-collapsed IME
+
+_Check composition on non-collapsed selection_:
+
+* Hiragana,
+* Spanish-ISO: accent (it's under `'`) + "a",
+* MacOS: long "a" press (accent balloon).
+
+**Expected**: Composition should be started correctly, character starting the composition should be visible. The selected
+text should be replaced by composition start character.
