svg insert shape string bug

svg insert shape string bug

not support custom areaProps attributes ???

const svg = document.querySelector(`[data-uuid="live_map_svg"]`);

svg.insertAdjacentHTML(`beforeend`, svgPolygon);

svgPolygon = `<polygon stroke="" fill="#DB524F" points="454.99798583984375 586.333984375 534.9979858398438 586.333984375 534.9979858398438 719.6680297851562 454.99798583984375 719.6680297851562" center='{"x":494.99798583984375,"y":653.0010070800781}' areaprops='{"id":10202,"activityEventId":2801,"ticketCategoryId":11201,"desc":"_贵宾区","name":"贵宾区","floor":0,"sort":0,"status":1} uuid="polygon_1583483461614_10045"></polygon>`

missing ' single quote bug 😂 ⚠️

OK
