Problem
DropDownDiv.clearContent() already clears the width set on the style of the content div, but it doesn't clear the height. in Blockly 12.0.0-beta4 dropdown fields now set the height of the content div which ends up affecting other field editors
Request
DropDownDiv.clearContent() should also clear any height set on the dropdown div
