JAWS reads rounding error on min value of range input

[jessegreenberg]

Summary

Certain combinations of min and max attributes on <input type="range"> will cause JAWS to read extra decimals when reporting the min attribute while reading through the content with the virtual cursor. For example:

1. Go to https://jsfiddle.net/au7rhbg8/31/
2. Read through the content with virtual cursor, when JAWS reaches the slider it will say

"Value Slider, 0.6, min 0.100...001, max 1"

Expected result

I would expect JAWS to report the min value as "0.1".

Actual result

JAWS actually reads a wrong value with incorrect precision, like "0.100...001"

Example

See the above JSFiddle for an example.

note: this occurs in virtual cursor when announcing the 'min value' JAWS announces a long string of numbers

example from speech history for the test case:

Value Slider left right slider
