When assigning a lambda to a variable right after an if statement, the parser seems to understand that a ternary expression is happening when in fact it is not.

### Steps to reproduce

Put the code bellow on a script on an empty project
```gdscript
func test():
	var v
	if true: v = (func(): test())
	if true: v = (func(): test())
	if true: v = (func(): test())

	if true: v = func(): test()
	if true: v = func(): test()
```

					r_state = DOC_LINE_IN_CODEBLOCK;
					buffer_start = from;
				}
			} break;
			case DOC_LINE_IN_CODE: {
				int pos = line.find("[/code]", from);
				if (pos < 0) {
					process = false;
					break;
				}
				from = pos + 7;
				r_state = DOC_LINE_NORMAL;
			} break;
			case DOC_LINE_IN_CODEBLOCK: {
				int pos = line.find("[/codeblock]", from);
				if (pos < 0) {
					process = false;
					break;
				}
				from = pos + 12;
				if (pos == 0) {
					line_join = "\n";
				} else {
					result += line.substr(buffer_start, pos - buffer_start) + '\n';
				}
				result += "[/codeblock]";
				if (from < len) {
					result += '\n';
