Created attachment 276574 [details] test case Particularly, input[type=search] fields are taller than other text input fields given the same styling. There is a difference in height of about ~3-5px depending on the specified font-size + line-height Somehow the ::-webkit-search-cancel-button makes the field taller. It seems to inherit the font size, its box becomes taller and grows the parent box (<div pseudo="-webkit-textfield-decoration-container">). Hard to guess what exactly is going on though as the inspector in TP2 does not display the shadow DOM like it does with Safari 9.1. [ input[type="search"]::-webkit-search-cancel-button { -webkit-appearance: none } seems to ‘fix’ the problem - but then I have to style the whole thing myself ] In the testcase: various form controls in a row, styling based a real world stylesheet. The search field stands out as taller.
