Repro:
1. Steal spell whose cast point is longer than 0.15s.
2. Cast it.

Result:
The cast point countdown can't run over the whole icon, causing the countdown ends without 360 degrees prematurely.

Expected:
The cast point countdown total progress should be matched the actual cast point on Rubick, which is min(0.15, original cast point) without "DOTA_ABILITY_BEHAVIOR_NORMAL_WHEN_STOLEN" or original cast point with the flag, instead of using the spell original cast point in any cases.
