Notable tooltip in Heroic tragedy range incorrectly display information

Steps to reproduce :
- 1) Open your passive skill tree (P)
- 2) Put Timeless Jewell Heroic Tragedy (Vorana) in a jewel node
- 3) Put your mouse pointer onto a new modified Notable (ex : Winter Forest)
- 4) Press Alt to display additional informations in the Notable tooltip (ex : Ice shot - dmg per sec 19000 -> 23000)
- 5) Put your mouse pointer away to make the tooltip disapear
- 6) Put your mouse pointer onto the same Notable on step 3 to display the tooltip
- 7) Press Alt to display additional informations in the Notable tooltip

Expected Behaviour :
- The tooltip displays same informations than step 4 (ex : Ice shot - dmg per sec 19000 -> 23000)

Actual Behaviour :
- The tooltip displays wrong informations based on number of times the user moves the mouse pointer in and out.(ex : 3 moves in and out displays : Ice shot - dmg per sec 19000 -> 31000)

Incorrect display : [dmg -> dmg + N * inc_dmg] where N is the number of times the mouse pointer moves in and out from the Notable.

This incorrect behavior happens only on Notable in Heroic tragedy range. Small passive nodes in jewel range are not affected, neither nodes out of jewel range.
