**User story:**
As a Wikidata editor using the UI,
I expect the page title to always be up-to-date (what I see after saving/canceling should match what I see if I then refresh the page)
in order to avoid confusion.
**Problem:**
When displaying an Item or Property page, the page heading usually applies language fallback to the label and description. The problem is that doing anything with the termbox which causes the heading to update causes the language fallback to no longer be applied
**Examples:**
e.g.
* On https://test.wikidata.org/wiki/Q38378?uselang=de-ch `de-ch` falls back to `de` for the label and `en` for the description
* On https://test.wikidata.org/wiki/Q38379?uselang=de-ch `de-ch` falls back to `en` for the label and `de` for the description
Doing anything with the termbox which causes the heading to update causes the language fallback to no longer be applied
**Steps to reproduce:**
* Make any change and save it. After saving the heading is refreshed and no longer applies language fallbackA
* Make any change to the language currently set as the interface language, no save needed. The heading updates immediately, no longer applying language fallbackand save it.
* After saving the heading is refreshed and no longer applies language fallback
B
* Make any change to the language currently set as the interface language and then cancel editing., The heading updates when making the changes, the changes are reverted after cancellingno save needed.
* The heading updates immediately, but language fallback is no longer appliedno longer applying language fallback
**Solution:**C
* Make any change to the language current set as the interface language and then cancel editing.
* The heading updates when making the changes, the changes are reverted after cancelling, but language fallback is no longer applied
**Notes:**
* This is a side-effect of T98014. PHP does language fallback in the header section, but JS does not. So, if you edit the terms of an entity which doesn't have terms in the UI language, after leaving edit mode the header section might look different than it does after a reload.
* This will get more visible after releasing language code mul`mul` (T285156).
**Acceptance criteria:**
[] The page title is always up-to-date as expected.
