@Jpita: Assuming this task is about the ContentTranslation code project, hence adding that project tag so other people who don't know or don't care about team tags can also find this task when searching via projects (currently nobody could find this task as it only had some old and archived (!) team project tag). Please set appropriate project tags when possible. Thanks!

Some related issues to consider:

• Once a warning is shown the percentage of MT is not updated until the focus leaves the paragraph This is problematic since it does not allow to see the user how the content is improved as the user edits (unless taps outside or adds a link, etc.) This is captured in T263116: Once the MT warning is shown for a paragraph update it as the user edits its contents
• The algorithm for the comparison may be affected by the amount typing without spaces. Which is worth investigating by using this example since Thai may be relevant language for this.
