Steps to reproduce:

1. Create a step against an element which could be identified by TextContent. The text should contain comma. 

2. Convert the step in code and try to execute the test. 

3. The coded step will fail with Element Not Found exception showing the expected string does not contain the comma. 

Please find attached a sample project demonstrating the issue. 

Note: If TextContent is changed to InnerMarkup the element will be successfully found.
