positron Nothing displays when I hover over an item while viewing an R data frame

Discussed in https://github.com/posit-dev/positron-beta/discussions/230

^{Originally posted by smach June 26, 2024} When I view a data frame in RStudio and hover over a value that doesn't completely display in the viewer panel, such as a long string, I see a larger number of characters in the tooltip than I do on screen. That didn't happen when I viewed a data frame in Positron. The robust variable viewer is one of the things I like most about RStudio and miss in VSCode.

A simple repro case:

x <- data.frame(a = "an extremely long sentence -- or at least, one that's likely to exceed the boundaries of the data explorer's individual cell.")
View(x)

Positron:

Putting this into Release candidate for now, as we do want to support long text, but avoid having to display it all at once and overwhelm the rest of columns.
