List of steps to reproduce (step by step, including full links if applicable):

• Open [[Special:ContentTranslation]]
• Translate an article
• Publish the translation

• Do some changes to the original article
• Start translating the article

What happens?:
You will be prompted into editing the translation you already published, without having any way to start translating the newer version of it.

What should have happened instead?:
Start translating the last revision of the article or be able to choose whether to do it or start editing the revision you had already published.

Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc:
This is happening when traslating an English article in Italian (on itwiki), but that's likely an universal issue.
