pinch not active on mobile Android and Ios on line chart

the canvas touch-action is not detected by chartjs on iphone (safari) and galaxy s25 (chrome) . It is impossible to zoom , pan .

My config is
`zoom: {
wheel: {
enabled: true,
},
pinch: {
enabled: true,
},
mode: 'xy',
threshold: 2,
sensitivity: 2,
onZoomStart,
},
drag: {
enabled: true,
},`

I override css styles canvas with touch-action:auto but it zooms page and not the line chart.

Start by reproducing the supplied zoom and drag configuration on iPhone Safari and Galaxy S25 Chrome, then inspect how the canvas touch-action behavior is handled. Done means pinch zoom and pan affect the line chart on both devices without zooming or panning the page.
