As you can see from the screenshot, when using the dot character class the text shown in the Tools section is wrong. . Matches any character except linebreaks. Equivalent to [^\n\r].

This is because you have the s (aka dotall) flag enabled, which allows . to match line breaks. The dynamic hints recognize that, but the documentation is static. We should add a note about dotall to the docs though.
