描述

UI gets stuck when I scroll horizontally and makes the page unresponsive in Chrome. I am using 4.10.0 version of UI-Grid. My table has 10 columns and the data is limited to 50 rows per page.

I have already tried setting "columnVirtualizationThreshold: $scope.columns.length", but this didn't resolve the issue. Any help on resolving this is much appreciated.

研究方向
Investigate the scrolling behavior in UI Grid's core library, particularly the grid scrolling and virtualization logic. Look at files like 'grid.js' or 'ui grid scroll.js' in the source code. The issue mentions a horizontal scroll freeze; check if it's related to column virtualization thresholds. There is no linked PR or maintainer response, so the fix may require reproducing the bug in Chrome and analyzing the event handling. Consider if the issue is caused by a known Chrome bug or UI Grid's repaint logic.
