If the HTML from the theme or other plugins is not very well formatted, it can sometimes cause issues when using TranslatePress.
For example, using duplicated attributes in a tag can cause missing attributes, which in turn can lead to unexpected behavior of the website when browsing a translated page.
We have solutions that attempt fixing broken HTML.
