Fix incorrect comparison

[Horstage]

Motivation and context

I have seen this error in the code and wanted to provide a fix. Doing so via GitHubs tools was the fastest way.

How has this been tested?

Not at all. I haven't even added a unit test for this.
This line of code was clearly intended the way I changed it.
I do understand however if you want me to properly test it, but this will take time.

@Horstage Thank you for your contribution!

@Horstage , could you please merge the latest develop branch? I hope it will solve problems with tests.

@dvkruchinin , could you please look at the issue? After the contributor merged 'develop', we still have failed tests. I'm sure UI tests should not be affected by the change.
