css - Row Wrap in flex-box not wrapping in Safari

Question

A flex container has four children, each with a flex-basis of 25% an a min-width. flex-flow is set to row wrap. Browsers other then Safari handle this as expected: if the min-width is reached, it wraps the the next item to the next row. In Safari it overflow the container.

Per a comment on bugs.webkit.org, it seems the solution is simple!

If your style is

div.flex {
    display: -webkit-flex;
    display: flex;
    -webkit-flex-wrap: wrap;
    flex-wrap: wrap;
    -webkit-flex-direction: row;
    flex-direction: row;
}
div.flex .item {
    min-width: 15em;
    -webkit-flex: 1;
    flex: 1;
}

you just need to add more explicitness to your flex declaration. In fact, I think only one line needs to change like so

div.flex {
    display: -webkit-flex;
    display: flex;
    -webkit-flex-wrap: wrap;
    flex-wrap: wrap;
    -webkit-flex-direction: row;
    flex-direction: row;
}
div.flex .item {
    min-width: 15em;
    -webkit-flex: 1 1 15em; /* this */
    flex: 1;
}
