Steps to replicate the issue (include links if applicable):

• Go to https://en.m.wikipedia.beta.wmflabs.org/wiki/Lightsaber# or any mobile view site
• Edit anywhere in the article and make at least a double space between the texts
• Create a story and select the line that has the double space, even though it will probably not show it when selecting
• Publish your story
• Edit your wikistory and you will see an outdated warning appear

What happens?:
The image in your wikistory shows up as an outdated warning. When you click on the image, it has the double space. When you click the replace that's next to the outdated error and select that same line, it only shows 1 space as seen in the video below.

What should have happened instead?:
The spacing that was originally edited should match the article in the Wikistory so it won't get an outdated warning

Software version (skip for WMF-hosted wikis like Wikipedia):
