[BUGZILLA #17851] Beginning of output in Rgui console lost

[github-actions]

Created attachment 2650 [details]
beginning of the output has disappeared

Start Rgui with shortcut and execute in the R console the following 4 lines:

# output 90 short lines followed by 1 very long line to console
ddd <- array("90 short lines", 91)
ddd[length(ddd)] <- toString(c(seq_len(600)))
print(ddd)

then the R console shows a few lines with no scroll box (screen shot added)
