No way to check if on long break or not, or any storage of the number. The number should increase and decrease in conjunction with the break time if it is stopped.
Resuming results on the timer being reset to the number set on break, not to the time on pause. This might apply to breaks that occur on auto switching mode and/or long breaks, will have to test further.
For example, if i'm on session at 60 minutes and switch to break at 5 minutes, when I switch to break it'll keep the same smaller font. It will only go back if I change the time of break, which I have currently selected.
Another example, if I'm on session at 60 and decrease by 1 minute to 59, there will be slight downward nudge to make extra space for the bigger font.
Possible solutions:
For switching time options - Make their be a font and sessionSeconds check on time option switch.
For the nudge on font size increase/decrease: Have set margin, content, padding, or something (figure it out) that will fit both so the nudge doesn't happen.
All of this only applies to '<= 420px' screen sizes, because that's where the font size changes happen.
