Text Shift Uncontrollably Inside Accordion Widget

guys hi! i've been crashing head 2 days this. hope provide help!

 

i have accordion widget long text block inside 1 of boxes (a list on 80 lines). on background each second line put grey rectange shape give contrast lines in list. in project rectangles prefectly aligned right behind lines. when publish site definately see rectangles shift or down.

 

is bug , widget cannon handle correctly many elements insie feiled or missing here?

 

many in advance advice!! might saving me insanity here;)

 

 

update!! it not shapes text shifting. fave items on list consists of 2 lines. that's changed leading betwin 2 lines 200% (for separate items in list) 146% between 2 lines (for items cosist of 2 lines of text). somehow couses text shift in preview mode xompared design mode. when make leading unilateral throghout entire textbox stands in place.

 

still problem remains unsolved.

percentage-based leading (line-spacing) rounded whole pixel amount in browsers , used fractional amount in others.

 

confirm "round leading whole number" setting turned on in "content" panel of site properties.

 

if use "web-safe" font text different in different browsers. if use web font there less variation in line layout between browsers , therefore less text line break different heights in different browsers.
