Descriptions over 10,000 characters don't work

Bug Description

From what I understand, the intention for descriptions over 10,000 characters is that HtmlDescription wrapper should display the first 10,000 characters, then a "Load more" button which would load the next batch of 10,000 characters. In Playnite, there are several issues with this:

1. If the description is over 10,000 characters - no description is shown. Only the Load more button is visible. Once you click on the Load more buttons nothing happens, and there is still no description is visible.
2. The Load more button is not selectable through normal controller/keyboard navigation in Fullscreen mode. You can only select it via Tab from your keyboard
3. I tried the PartialLoadEnabled="False flag so the full description is just shown. The Load more button becomes hidden correctly, but there is still no description shown.

This bug affects both Desktop and Fullscreen mode. Although I'm not fully sure if it has to do with TheArtOfDev.HtmlRenderer.WPF, the Playnite implementation or both.

In my opinion, since in Playnite the description is always local and not pulled from a webpage, it should be with PartialLoadEnabled="False by default. This also has the benefit that only the actual bug of descriptions over 10,000 characters not rendering needs to be addressed and the Load more button in Playnite can be removed.

One case to be considered is that when using a controller in Fullscreen mode, there is no equivalent of the "Tab" button. So there is no way to stop reading a long description while remaining on the same screen. However I think this should be addressed separately, as the same can be true for description with less than 10,000 characters.

To Reproduce

Have a game with a description over 10,000 characters.
