Unable to convert images with alt attributes to HTML element

[NayanAnsh]

The problem comes when Delta contains images with alt attribute. Below is Delta input

{attributes: {
{alt: 'sample alt'}, insert: {image:'data:image/jpeg;base64,/....'}}

output-
<img class="ql-image" src="data:image/jpeg;base64,/.....">
expected out put -
<img alt="sample alt" class="ql-image" src="data:image/jpeg;base64,/.....">
The delta is working correctly quilljs reader but for some reason when I convert delta to HTML then alt tags are missing

converter code -
var converter = new QuillDeltaToHtmlConverter(posts.body.ops,cfg); console.log("Data") converter.beforeRender((GroupType,data)=>{ console.log(data) }) var html = converter.convert(); // console.log("HTML----"); posts.body = html;
expected output -

output got -
