Word document that has spaces stripped when pasting

Pasting the attached document into a ContentEditable div removes three of the spaces.

Instead of "The quick brown fox jumps over the lazy dog", paste produces "The quickbrownfox jumpsover the lazy dog". This does not happen on other browsers.

Replication steps:

* Load a page with a CE element such as https://jsfiddle.net/97t0f3mt/
* Copy all content from the word document
* Paste in Safari
* Observe the incorrect content

I've used two versions of Microsoft Word - 16.10 (180210) and 16.13.1 (180523) - to replicate.

I cannot replicate this in 11.0.3 (11604.5.6.1.1), all spaces are included, suggesting that the word paste changes in 11.1 (bug 124391 and related issues) are the cause of this.

I have replicated the failure in:
11.1 (11605.1.33.1.4) - macOS 10.11.6 (this machine had 11.0.3 and has now been upgraded)
11.1.1 (13605.2.8) - macOS 10.13.5 Beta (17F70a)
Webkit Build Archive r232252 (also on 10.13.5 Beta)

Safari 15.5 matches other browsers

I am unable to reproduce it in Safari 15.5 on macOS 12.4 as shown in the picture. If I have followed any incorrect steps, please update this accordingly. Else, appreciate if this can be marked as "RESOLVED CONFIGURATION CHANGED". Thanks!
