Before, we constructed a leftwards conditional tree (`(_a_b = (_a = a) == null ? void 0 : _a.b) == null ? void 0 : _a_b.c`) instead of a rightward tree (`(_a = a) == null ? void 0 : (_a_b = _a.b) == null ? void 0 : _a_b.c`), which required multiple `== null` checks after the first nullish is found. **Related issue:** - Closes #7531.		2023-06-19 12:00:11 +09:00
