Column wrap is behaving differently in safari and in chrome.

[vishal9p]

I have a codepen designed where i have used column wrap for aligning the items.
CodePen Link:----->(below)

Steps to reproduce the issue:
Open the above codepen link in chrome and in safari,we can see the difference in the alignment(Attached the screen-shot).
SAFARI:->
In case of safari browser there is a extra space between the flex container and the flex items where the column wrap is applied.The width of the flex container is more than the children.
CHROME:->
In case of chrome browser there is no extra space between the flex container and the flex items where the column wrap is applied. The width of the flex container is exactly equal to the the children.That is there is no space between the flex container and flex item where this column wrap is applied.

**Now i am bit confused which behaviour is actually correct the chrome one or the safari.**Please clarify this.Using flex-direction:column instead of column wrap fixes the issue but i have to use column-wrap i cannot use column as the flex-direction.Also flex-grow:1 is not a valid solution.

So which behaviour is correct the chrome one, where the flex container takes width exactly equal to to their children or the safari one , where the width of the flex container is bit more than the child items.please clarify this and also provide the fix if any exist.

Snapshot of codepen in SAFARI:

Snapshot of codepen in CHROME:

(The issue can be seen visually by confirming the width of the items in the blue border.) The Gap beween the blue border and the green border is expected(thats why flex-grow:1 is rejected solution).
Also in actual code where this codepen is used i have added the vendor prefixes for the flex(so thats not a issue)

I'm not sure why this issue was filed in this repo, as it doesn't seem to have anything to do with the demos here.

If you've found a browser bug then you should file an issue with the relevant browser. Here's some good info on how to do that: https://developers.google.com/web/feedback/
