Line points corresponding to bars with 0 height are not accessible when no legend is highlighted

[krkshitij]

After the merge of PR #31197, line points on vertical bar charts are inaccessible when the bar value is 0 at the corresponding x-axis point. They become accessible only when the line legend is highlighted. For more information, see https://github.com/microsoft/fluentui/pull/31197#discussion_r1581021403
