Bug reported here by KaMan
I use newest Chrome for my tablet (build 67.0.3396.87, Android) in desktop mode of the interface.
I have no problem with suggesters on Special:NewLexeme page (like selecting Language of Lexeme).
I have no problem on newly created lexeme page when I select properties and theirs values for lexeme.
The problem comes when I'm trying to enter any form to this lexeme. I enter string representation of the form and language of the representation and then click with my finger on "Grammatical features" field. Then I start typing string of some item (for example Q146786). Suggester finds this item and highlights it. Then I select this item from suggester with my finger by single click on it. Then strangely whole page reloads and page with Q146786 is opened. I lost page with my lexeme. This way I cannot select anything with this suggester on my tablet.
