[Bug] Issues with funnel help button (i)

[rcontiuk]

What happened?

User found that there are some issues with the funnel help button that helps matching patterns. First issue is the following error returned:

The step configuration is:

Second, if an apostrophe is used in the pattern field, the help feature returns a valid pattern although the funnel condition is not met. Users should at least be warned that some values (maybe special characters) should not be used.

What should happen?

Matomo should not return an error and should have a better pattern verification.

How can this be reproduced?

User removed apostrophe and funnel worked afterwards.
