[BUG?] Filter Form in Statistics opens additional TYPO3 Overlay

[YannikSMYLIE]

Hey,
when I use the form to filter my clients (and only with the form!) the page gets a total reload, so that I have two TYPO3 Sidebars. I can continue with this for as many times as I want and get more and more Sidebars from TYPO3.
I tried to find a solution for that but I am a little bit confused where this comes from.

I experience the same issue in TYPO3 v12. Changing the form method from GET to POST (and reading the data from the body instead of the query params in ClientFilterDemandConverter) solves the issue, but then the back button cannot be used to navigate from detail to list view anymore.

Submitting the form using GET leads to a redirect response to /typo3/login?redirect=t3monitoring.Statistic_index&redirectParams=[...]. Might happen because of the missing parameter token but atm I don't have time to investigate further.

This change fixes the problem of the additional overlay. Both the links and the filter form work properly (thanks @nlehmkuhl for the hint). But as explained in the previous comment, the browser back button cannot be used to navigate back to the search result page anymore. Thoughts?

Same issue on my CMS v12 - so a +1 from me.

This issue has been resolved with commit d4d4bce which was released in v3.1.0.
