PickList Font Size in field editor not respecting theme

I’m looking for zero zoom. I’ve accomplished it with field editors and search components by increasing the font to 16px with CSS. The picklist isn’t working. I have sticky headers and footers with some model actions, queries rendering which probably add to the problem of the zoom out nor working . When it zooms in and I try to zoom back out: 1) it locks up for a few seconds and won’t allow any zoom. 2) Then it seems that I have to zoom by pinching certain parts of the screen. Like I have to have on finger on the body and thumb on the footer.
