Description
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.

Research direction
Reproduce the issue using the linked CodePen: box zoom a small chart region, then zoom out with the mouse wheel, and compare the background image against its x/y coordinate references. Trace the background-image rendering and zoom interaction paths, then confirm the image keeps the correct size and position after manual zoom-out, while double-click reset remains correct.
