Hi Team,

While going through Blink's commit, I came across this potential crash fix:

Blink Commit - https://src.chromium.org/viewvc/blink?revision=183919&view=revision

WebKit Source - https://github.com/WebKit/WebKit/blob/1105db4ef4beff2c87fbe05387c58123ee89ff97/Source/WebCore/platform/ScrollbarThemeComposite.cpp#L237

It does not have test case to confirm the crash etc but I just wanted to check if it is good to fix since from review comment, it does seems to be trigger easily in Windows platform.

Appreciate any input.

Thanks!
