Rmarkdown flexdashboard valueboxes do not render properly in Chrome or IE (but work in FireFox)

My flexdashboard works perfectly in firefox but in chrome or IE, the valueboxes don't render properly and they get hidden behind other page elements.

Showing in Firefox (on top) and Chrome/IE (on bottom):

Here is a reprex of my code:

       draggable = FALSE, top = "2%", left = "5%", right = "auto", bottom = "auto",
       width = '30%', height = 'auto',
       style = "background: white; border:3px solid #eaf2f8; color: #5d6063; justify-content: center;",
       p(strong("some text"))
   ) ```

I was able to fix this myself by removing the data-height=50 from the row containing the valueboxes. For anyone who comes across this error in the future. Chrome apparently interprets the CSS/HTML differently than Firefox. If anyone could provide input about why the occurs, I'd love to know.
