I've noticed a new tooltip saying:

"This setting specifies the size (in pixels) of an arrow (caret) that 
extends from a tooltip's body toward the data point. On a regular basis, 
a very small value - this setting's default has increased it 
significantly."

Can someone explain this non-native English speaker what the last part 
"- this setting's default has increased it significantly." is supposed 
to mean?

Thanks,
Koos
