1503626 - Missing min-width value in the flex item sizing properties list if min-width comes from the default value

Status: RESOLVED FIXED

(DevTools :: Inspector, defect, P3)

Description

[Patrick Brosset <:pbro>]

I haven't yet found a simpler test page for this, but here are some not too hard steps to reproduce:

- load https://codepen.io/
- open the inspector
- select the img.projects-screenshot element
- in the rule-view, toggle the max-width:100% property off
- select the div.projects-promo element
- head over to the flex item sidebar panel

--> The Minimum Size section is displayed, but it shows min-width:; (missing value)

This is because clamping on min-width did occur, but min-width was not specified by the author in CSS. It instead came from the browser's default auto value.

I think we shouldn't attempt to display the min-width property at all in this case.
Same thing goes for the Maximum Sizing section.
