How to reproduce:
CLick on the magifier to search for a Email
Problem:
I don't understand why there is a wastebin-symbol and a "X" symbol next to the searching filed. It's unclear why you would need both.
I'd expect to close the searchingsection by using the X-symbol. Actually you need to use the bin-symbol to do so (even though I don't know why you'd click on a bin to leave a section)
By using the X you only close the searchfiled which is not necessary I think, because it's juist a small field and you can see all the search results without closing it.
I think one function would be enough and the bin-symbol could be confusing. It would be fine to just have a X to leave the search- section.
I don't know if I'm the only one thinking that, but I think it's unnneedlessly complicated.
