Bug Report: Trendline snapping issue in ForexTester Online

Hello,

I would like to report a bug in ForexTester Online. When I try to draw a trendline, the line snaps only to fixed angles (0°, 90°, 180°), and it is impossible to make fine adjustments to the angle.

Interestingly, if I update Chrome to the latest version, the trendline behaves normally and I can adjust the angle freely. However, this is very inconvenient since I have to update the browser each time to avoid the bug.

Could you please investigate this issue and provide a fix?

OS:Mac
Google Chrome version 139.0.7258.128（Official Build） （arm64）

Thank you.
