在 rubymine 4.5.3 中，我尝试运行一个场景：
Scenario: I want to buy icecream, then watch a movie
Given I am at a mall
When I buy icecream
Then I should be allowed to watch a movie
该场景包含一个逗号，因此当我右键单击并点击播放时，元素名称过滤器如下所示：
I want to buy icecream\, then watch a movie
但后来我得到了这个堆栈跟踪：
too short escape sequence (ArgumentError)

C:/ruby193/bin/cucumber:23:in `<top (required)>'
-e:1:in `load'
-e:1:in `<main>'
为了解决这个问题，我更改了元素名称过滤器，并删除了反斜杠：
I want to buy icecream, then watch a movie
现在场景运行正常。
难道我做错了什么？
编辑：刚刚确认双引号也会出现同样的问题
编辑：确认问题仍然存在于 RubyMine 4.5.4
