放置 labelAlign: 'top' 时，FieldContainer 无法正确显示。

找到我的小提琴：https ://fiddle.sencha.com/#fiddle/1c2s 我创建了一个基于字段容器的自定义字段。如果将窗口调整为更小的尺寸，您会看到文本字段将位于 fieldContiner 上方。

关于如何解决这个问题的任何想法？任何解决方法？我已经尝试了几件事，但我很挣扎......我现在无法采取行动来改变这个......而且我肯定需要解决这个问题。

提前致谢

确实看起来像错误，但有一种非常简单的方法可以使这项工作 - 只需设置minHeight: 65到您的 url 字段。

我很确定我找到了答案。build src 和 doc 不匹配！

如果您签入文件的构建源，src/layout/component/field/FieldContainer.js您会注意到它与文档不对应（尤其是缺少某些方法，例如calculateOwnerHeightFromContentHeight）。

注意：这已在 ExtJs 6.2.0 中修复

建议覆盖以解决此问题：

/**
 * Override to fix componentLayout wrong calculation of height when labelAlign='top'
 *
 * See post forum:
 * {@link https://www.sencha.com/forum/showthread.php?311212-Fieldcontainer-incorrectly-displays-in-toolbar-with-label-aligned-top}
