Description Jack Hill 2022-08-17 23:12:44 UTC 
SUMMARY
The effective module width seems to be calculated based on the length of the text under the slider. Since some slider values have longer text than others, this causes the width to change between these values. This means:
1. The slider changes length, and therefore the slider grooves actually change place while the user is moving the handle
2. The bullet points move left/right

Both of these are quite jarring, but issue 1 is the worst. When moving the slider between grooves 2 & 3 (assuming left=0 and right=4) the page flickers between the two values.

STEPS TO REPRODUCE
1. Move the slider through all different values
2. 
3. 

OBSERVED RESULT
The effective page width changes size

EXPECTED RESULT
The page width should be calculated based on slider value with the longest width
