Issue with legend

[AlaaEddean]

we are using Chartjs for some graphs and having an issue with clickable legend boxes, as they are being displayed in some cases and not displayed in other cases as in the below snapshots :
without : https://ibb.co/cDgHaF
with : https://ibb.co/mkCjNv

The case that we have observed for displaying these boxes is when the page auto refreshes while it is minimized.

here is the Canvas HTML:

<canvas width="1200" height="600" id="canvas_F2" class="justshowme" ></canvas>

here is the chart option:

			var lineGraph = new Chart($("#canvas_F2"), {
				type: 'line',
				data: chartdata2,
				});

and here is the refresh meta tag:
<meta http-equiv="refresh" content="300">
Can anyone please let us know what is wrong here?

Thanks a lot in advance

This is hard to debug without a fiddle that reproduces the issue. It's likely related to how we detect resizes of the canvas container. Likely fixed in #4596
