[BUG]: Background image is rendered at an incorrect size after box zoom followed by mouse wheel zoom out

Description

On charts containing a background image with xref: "x" and yref: "y", performing a box zoom followed by a manual zoom out causes the background image to be rendered with an incorrect size and position. It no longer matches the coordinate system defined by xref and yref.

Steps to reproduce

Here https://codepen.io/JulienIcon/pen/QwdBypd, try to box zoom a small part of the chart and then try to manually zoom out using the mouse wheel

Notes

If the zoom is reset using the default double-click interaction, the background image is rendered correctly again.

Riproduci il problema usando il CodePen collegato: esegui un box zoom su una piccola regione del grafico, quindi fai zoom out con la rotellina del mouse e confronta l’immagine di sfondo con i relativi riferimenti alle coordinate x/y. Traccia i percorsi di rendering e di interazione dello zoom di background-image, quindi conferma che l’immagine mantenga dimensioni e posizione corrette dopo lo zoom-out manuale, mentre il double-click reset rimanga corretto.
