Bug 140540

I raised this issue to the www-list here https://lists.w3.org/Archives/Public/www-style/2015Jan/0041.html. Summarizing, the current algorithm does not really enforce the condition of "base size <= growth limit". Not fulfilling it makes the algorithm produce invalid results as explained in the email. Using the example mentioned there: <div style="display: grid; grid-template-columns: minmax(40px, min-content) minmax(50px, max-content);"> <div style="grid-column: 1 / -1;" id="item1"></div> <div style="grid-column: 1;" id="item2"></div> <div style="grid-column: 2;" id="item3"></div> </div> Let's use the following sizes (min-content,max-content) in pixels for the items: - item1: (40, 90) - item2: (10, 10) - item3: (10, 10) The track sizing algorithm will generate the following outcome, for the (min,max) sizes of tracks: (40, 30) (50, 60) which means that with enough space the grid will be 40+60 = 100px wide when it should be enough with 90px.
