Translation with status "maschine translated" outdates after date refreshing

[MizukiTemma]

Describe the Bug

Translations with status "maschine translated" are "outdated" after refreshing the date of their source translation.

Steps to Reproduce

1. Set two languages (for example English and Arabic) directly hanging from German (root language) in the language tree of a region.
2. Create a German translation.
3. Create an Arabic translation by MT, and create an English translation manually (not by MT)
4. See in the page tree that the German and English traslations are up-to-date (✅) and the Arabic one maschine-translated (🤖)
5. Open the German translation and click the button "Mark this page as up-to-date"
6. Go back to the page tree, see the German and English translations are up-to-date but the Arabic one is marked as outdated (⚠️)

Expected Behavior

The Arabic translation should be up-to-date too.

Actual Behavior

The Arabic translation is outdated.

Additional Information

👀 The cause seems to be the order in which the translations are refreshed: after this reproduction procedure the German translation (version 2) and the English one (version 1) have time stamp of 16:04:12, where as the Arabic one 16:03:38.
