Editting saved highlight annotations

[hamad12a]

As a first step, I have tried to achieve that by making this.data.hasOwnCanvas = true; in annotation.js to separate the highlight annotations canvases from the rest of the pdf rendered content, but the problem is the highlight effect now covers the entire highlighted text (saved highlighted text).
(Attached images have applied sepia and brightness filters to the entire pdf.js app. The higlight color is default #FFFF98 and fill-opacity="1" by default).

This image is obtained based on default configuration of class HighlightAnnotation:

This image is obtained after this.data.hasOwnCanvas = true;:

Yep we know this issue...
It's why when editing we just re-render the page but the editable annotations and then we draw the highlights in a svg layer which just on top of the canvas.

I appreciate the reply!
I consider myself as a novice and just an enthusiastic using pdf.js reader for reading my pdf docs with a little knowledge in programming logic. Within that said, do you mean that it's a bug or kind of not implemented yet?
Can't we find a workaround for the moment?
