Newsletter subscribe button title wrapped

[gilles6]

Preconditions

1. Magento 2.2.1
2. PHP 7.1

Steps to reproduce

Set the newsletter subscribe button's title with at least two Chinese characters (either by changing it with your browser's Developer Tool or by switching the CMS language to Chinese), for instance "订阅".

Expected result

The two characters of the Chinese word "订阅" should be written in the same line.

Actual result

The Chinese word "订阅" is wrapped in two lines.

I fixed the issue temporarily by adding the following CSS in the file web/css/source/_extend.less of my custom theme.

button.action.subscribe.primary {
  white-space: nowrap;
}
