The implementation of this conditional fails to consider that the corresponding stereotype capability could have a non-String value (including null), which would produce unexpected behavior. The revised implementation will only perform the case-insensitive comparison if the capability in the session request and the node stereotype both have String values.

The merge operation that necessitated this special-case handling has been eliminated. The session factory shouldn't be altering clients' requested capabilities.

// is provided
// they are mutually exclusive
MutableCapabilities filteredStereotype = new MutableCapabilities(stereotype);
if (capabilities.getCapability("appium:app") != null) {
filteredStereotype.setCapability(CapabilityType.BROWSER_NAME, (String) null);
}

capabilities = capabilities.merge(filteredStereotype);
LOG.info("Starting session for " + capabilities);

This test has been updated to verify the revised behavior, in which all extension capabilities with complex values are ignored for purposes of node matching.

I think it is a good idea to create a new test and let the existing test be as it is to verify the changes don't cause a breaking change for the users.

I restored the original test, altering the method name and inverting the expectation to correspond with the revised behavior.
