fix(monitoring): add `kiosk` for automatic height calculation to work

passing `height=-1` for automatic calculation of height, was broken
for a few releases, in this release it should work when `kisok` parameter
is also being passed

(cherry picked from commit 9282de2f99b84dc65a2d5a83390f075adb9922d7)
