Issue
It seems the advancedsearch temporarily stores its search text in the text area and then quickly removes it. This creates a jarring experience.
Steps to reproduce:
Actual
Note that just before it loads the advanced search interface it shows "bots intitle:test" temporarily. Then a few seconds later the intitle part is hidden. See, https://imgur.com/a/Jad6qd0 .
Expected
It just shows "bots" within the input box.
Notes
This may yet be another drawback of not implementing a critical interface using html, and building it using javascript. Aside from the "jumpy" nature of the loading, it also feels as if pushes the text from the input box to the "advanced parameters" area.
