Dataset search results page layout is broken by a long string in description

A long text (without whitespace) in the dataset description overflows dataset search results and makes the page layout broken. See screenshot below.
This is also visible in version 5.3 as well as on our 4.20 fork using

• Safari - Version 14.0.3 (15610.4.3.1.7, 15610)
• Chrome - Version 89.0.4389.82 (Official Build) (x86_64)
• Firefox - 86.0.1 (64-bits)

It is this dataset that is causing it: https://dataverse.nl/dataset.xhtml?persistentId=doi:10.34894/EPQT6D
The description contains:
,"timestamp","tag.ID","longitude..decimal.degree.","latitude..decimal.degree.","height.above.mean.sea.level","ground.speed","heading","location.error.numerical","GNSS.satellite.count","GNSS.satellite.visible","GNSS.maximum.signal.strength","GNSS.fix.type","GNSS.time.to.fix","year","month","rowID","watersensor","watersensorfreq"

It is along string without whitespace, somehow the browser won’t break at the ',' it seems to need whitespace.
We could ask the depositor change the metadata, add whitespace after the ',', but this should be solved by CSS.

Reproduce the dataset search results layout using the linked dataverse.nl dataset, especially its long description string, in Safari, Chrome, or Firefox. Inspect the CSS affecting dataset descriptions and confirm that the page no longer overflows or breaks when the description contains a long string without whitespace.
