调研方向
从 checkbox-theme.scss 第 88 行附近开始，在卡片或类似的容器元素中复现一个带有长标签的复选框。针对报告的 overflow 检查现有的 typography 和 layout 规则，然后验证长标签会换行成多行，并且复选框在左侧垂直对齐。

描述
Bug, feature request, or proposal:
Bug?
What is the expected behavior?
Checkboxes with long labels won't word wrap (as it did in earlier versions). (see bottom part of attacjed image)
What is the current behavior?
The labels of checkboxes will overflow the containing element. (see top part of attached image) The problem appeared when I upgraded to Angular 5 from 4-something and I pushed up material at the same time. It's possible this behavior was introduced in an earlier version of material than the latest.
What are the steps to reproduce?
Just make a checkbox with a long label inside a card or something.
What is the use-case or motivation for changing an existing behavior?
I have a checkbox on a login-page with a long text-string about the user agreeing on this and that. When wrapped it's about three lines with the checkbox vertically aligned on the left side.
Is there anything else we should know?
I solved it locally by altering _checkbox-theme.scss from line 88:
@mixin mat-checkbox-typography($config) {
.mat-checkbox {
font-family: mat-font-family($config);
}
.mat-checkbox-label { // NEW
white-space: initial; // NEW
} // NEW
// TODO(kara): Remove this style when fixing vertical baseline
.mat-checkbox-layout .mat-checkbox-label {
line-height: mat-line-height($config, body-2);
}
}
