Code Editor: If condition expand/collapse doesn't work if "&" operator is used

Version Information (please complete the following information):

Describe the bug

If a IF condition contains multiple tests with & operator then the IF is not recognized for automitic expand/collapse regionalization and is always expanded.

To Reproduce

Steps to reproduce the behavior:

1. Create IF condition with only a single value test. Expand/collapse works
2. Add additional test to the IF. Expand/collapse no longer works
