autosize: fit does not work accurately when combined with axis exprs

[fysherman]

I am building a chart with dynamic data and aiming to display axis labels in a way that is appropriate for each scenario. When I create a chart using 'autosize: fit' and combine it with expr in labelAlign, labelAngle, or labelExpr, at a certain width, the chart will have a fitting issue where a portion overflows outside the view. As the example below, a part of the chart, namely the legend, is missing, and the legend becomes visible when the width is set larger. If I directly set values for labelAngle and labelAlign instead of using expr, the chart renders correctly.
