Missing keywords from metadata, multiple DescriptiveKeywords not recognized [4.4.2]

[Bear-LB]

Describe the bug
Using Geonetwork 4.4.2
We harvested a bunch of metadata, and the keyword section of the metadata looks like this

<gmd:descriptiveKeywords>
	<gmd:MD_Keywords>
		<gmd:keyword>
			<gco:CharacterString>KEYWORD 1</gco:CharacterString>
		</gmd:keyword>
	</gmd:MD_Keywords>
</gmd:descriptiveKeywords>
<gmd:descriptiveKeywords>
	<gmd:MD_Keywords>
		<gmd:keyword>
			<gco:CharacterString>KEYWORD 2</gco:CharacterString>
		</gmd:keyword>
	</gmd:MD_Keywords>
</gmd:descriptiveKeywords>

This in turn means that on the searchpage, it's not possible to search for "KEYWORD 2"
only "KEYWORD 1" would be included.
Here's how it looks while looking at the metadata default view

This behaviour was not present in v3.2.X . Keywords were included from multiple DescriptiveKeywords sections in Version v3.2.X

A manual fix for us would be to change the keywords to be like this and then it would work.

<gmd:descriptiveKeywords>
	<gmd:MD_Keywords>
		<gmd:keyword>
			<gco:CharacterString>KEYWORD 1</gco:CharacterString>
		</gmd:keyword>
		<gmd:keyword>
			<gco:CharacterString>KEYWORD 2</gco:CharacterString>
		</gmd:keyword>
	</gmd:MD_Keywords>
</gmd:descriptiveKeywords>

But if we had to do this everytime we had to Harvest from upstream, that would be troublesome. Is there a way to fix this ?
Or Is it working as expected and it's our service providers job to fix their metadata ?

Thanks for your time

Can you check with #7843 ? Also it is not really recommended to encode keyword like this, it will make the editor form more complicated, it is better to group keywords by thesaurus - and those not part of a thesaurus together.

And way more keywords are showing up in search page.
