Hi there,
In the Bryntum Big Dataset Demo, navigating between tasks using the right and left arrow keys moves the focus correctly in sequence. Similarly, using the up and down arrow keys shifts focus to the first task in the previous or next row as expected.
However, in our Salesforce orgs, the arrow key navigation behaves inconsistently. Sometimes tasks are skipped, and other times entire rows are bypassed. The behavior appears random, and we haven't been able to identify a clear pattern. We also tested this on the Bryntum Examples Salesforce org and observed the same issues, which suggests that the problem may be related to how Bryntum operates in the Salesforce environment.
