Form submission failing if any browser Cookie has two or more encoded spaces
Hello, We have been having an issue with our embedded forms submissions not getting logged/saved in Marketo... This only happens if the user that submitted the form has a (can be any name) cookie with a value that has two or more encoded spaces (yes it can have one, but no more!). We have tested on a mkto landing page with no extra scripts and only a single cookie in the browser with the two or more encoded spaces, submit the form, then check for the user activity but nothing will be there. As soon as we clear the cookie or reduce the encoded spaces to one or none then submit the form we see the form activity.
Example Cookie value that will fail
Encoded: my%0Acookie%0Ahas%0Afour%0Aspaces
Decoded: my cookie has four spaces
Example Cookie value that will work
Encoded: mycookie%0Ahasonespace
Decoded: mycookie hasonespace
Curious if anyone else has seen this issue?
