Hovertemplate not using single text value for all data points

Hi there 👋, stumbled across this issue while playing around with hovertemplates in Plotly.NET.

The text property can be either set with an array of values (-> every data point gets its own text for hover display), or with a single value (-> every data point gets the same text)

This works well unless the text is used in a hover template. When using an array of text, these values are displayed correctly. But when using a single text for all datums, it does not display on hover.

Expected behavior: Hover template uses the single string of the text property for each hoverlabel
Actual behavior: Hoverlabels display %text

Here is a jsfiddle: https://jsfiddle.net/vsm79h3q/

Inizia riproducendo il comportamento di hovertemplate nel jsfiddle collegato, confrontando una proprietà text con valore array con una singola stringa. Traccia la gestione di hovertemplate per i valori di testo scalari e verifica che la modifica completata visualizzi la stessa stringa in ogni hoverlabel invece di %text.
