"Error during result rendering" with table containing very long syms or strings

[adavies42]

When trying to display a table of ~20k rows containing a sym column with syms of up to ~1.4MM characters, studio reported

An unexpected error occurred whilst communicating with `:<host>:<port>

Error detail is

Error during result rendering

and some cells of the sym column were rendered as empty, even though select count i from t where 0=count each string c showed they weren't.

Querying update string c from t resulted in the same error dialog, but the cells weren't drawn as empty anymore.

Can you provide a reproduction using built-in data generation? I'm not seeing any errors for these (although they are slow):

a:([]c:`${1400000?" "}each til 10)
a:([]c:{1400000?" "}each til 10)
