Storybook: Actions: Truncate string arguments

[juliandavidmr]

Describe the bug
When launching an action and it contains a string argument, the spaces are truncated.

To Reproduce

I have the next action definition:

typingEvent: action(`(ngModelChange) event`)

An input component of angular with the next event:

(ngModelChange)="typingEvent($event)"

Event (ngModelChange) launches the following example string: "ddddddddddddx       "
but Storybook show "ddddddddddddx ", that is, truncate all spaces to just one.

Expected behavior
That the output be shown as it was received.
