The Search tab's Find mode stacked four ClideFilterBoxes (search,
replace, include, exclude) that all looked identical: every box drew the
magnifying glass and the hint was only a semantics label, never visible
text — so they read as four blank search boxes. Render the hint as
placeholder text while empty, and make the leading icon optional (the
replace + glob fields pass icon: null). General win — every filter box
now shows its placeholder.
