屏幕阅读器无法读取Chrome上的数字输入值

Question

我有一个看起来像这样的旋钮：

<input type="number" name="amountMonthly" id="amount-monthly_0" class="formInput" required="required" tabindex="70" aria-describedby="amountMonthlyInfo" aria-labelledby="amountMonthlyLbl">

使用屏幕阅读器（我使用NVDA）时的预期行为是让它读取标签一次，并在旋转按钮中每次更改时读取新值。以下是在两个不同浏览器上以三种状态读取此元素的方法。

FIREFOX: Empty field selected (in focus)
    [label] spinbutton invalid entry required [description] edit blank
FIREFOX: press up button (increment)
    [number on screen]
FIREFOX: selected the entire numerical value (call it num)
    [first length-of-num characters of label] selected

CHROME: Empty field selected (in focus)
    [label] spinbutton editable invalid entry required [description] [label]
CHROME: press up button (increment)
    [label]
CHROME: selected the entire numerical value (call it num)
    [first length-of-num characters of label] selected

这显然是Chrome本身的一个错误。我找到了一个未解决此问题的人的未解决问题here。还有一张相关的NVDA门票，可以找到here。
