Hello Scott,

I moved this to the public Feedback Portal so you can Follow its status: https://feedback.telerik.com/blazor/1443720-selection-does-not-work-when-clicking-on-the-checkbox-works-when-clicking-the-row. I am marking it as a regression, because I am reasonably certain that it worked as expected in the previous version and when I wrote the documentation (it's next to impossible to actually test because of the updated framework dependencies) - and this will raise its priority a lot.

A workaround I can offer for the time being is using the previous version of the themes from Oct 25, you can find the full list here: https://github.com/telerik/kendo-themes/releases. The issue is in their latest versions, so something like this should work (this is for a server app, remove one of the @ symbols for a client one):

<link rel="stylesheet" href="https://unpkg.com/@@progress/kendo-theme-default@@4.6.0/dist/all.css" />

for the bootstrap theme

<link rel="stylesheet" href="https://unpkg.com/@@progress/kendo-theme-bootstrap@@4.4.0/dist/all.css" />

and for the material theme

<link rel="stylesheet" href="https://unpkg.com/@@progress/kendo-theme-material@@3.3.8/dist/all.css" />
