PivotTable does not hide UI for configured heatmap aggregation

[Flaurite]

Environment

Jmix version: 2.7.6

Steps To Reproduce

1. Go to https://demo.jmix.io/ui-samples/sample/pivot-table-ui-properties?tab=Description
2. Then select:
   • Heatmap
   • Sum
   • Tip
3. Disable UI mode by clicking button

Current Behavior

Nothing changes, and exception occurs in the console (attached not obfuscated stacktrace):

Uncaught TypeError: Cannot read properties of undefined (reading '0')
    at pivot.coffee:55:36
    at JmixPivotTable._getAggregationOptions (jmix-pivot-table.js:626:38)
    at JmixPivotTable._preparePivotTableOptions (jmix-pivot-table.js:300:39)
    at jmix-pivot-table.js:265:42
    at JmixPivotTable._recreatePivot (jmix-pivot-table.js:276:15)
    at JmixPivotTable._updateOptions (jmix-pivot-table.js:759:14)

Expected Behavior

UI of PivotTable should be hidden.

After further investigation, it turns out that the PivotTable is recreated from a configuration that does not consider some properties selected in the UI.
For now, we won't fix this issue, since changing the "showUI" property at runtime is not recommended. In the UI samples, it is included for clarity to demonstrate how it works.
