Developer Experienced In The Core Functionality Of FabricJS IText

I have a project with fabricjs with an extension of the IText object that allows a user to essentially use rich text editing. We build an object of character styling in php and parse that into the "styles" object of the extended IText to create the initial style of the document text. This all works for the most part but fabric is extremely buggy and we have some issues: 1) When pressing enter to create a new line the styling of the previous line doesn't carry forward. We managed to fix this by altering one of the fabric methods but it now doesn't work if you press enter twice to create a blank line - no style is brought through. 2) for some reason on some fonts we can't select the last character on a line All of this has something to do with the way fabric shifts styles across blank lines but we don't know fabric well enough to diagnose this efficiently. We will need to give you a working example of what is going on. Please don't bid on this project if you don't know how fabric works internally, just being able to use fabric isn't good enough as you will need to look at our extension of the IText and the internal workings of fabric to fix this issue. You will need to know how to use GIT as well, we will provide a development server with the entire project. You will also need software that can use file watchers to minify css and js on the fly as well as convert SCSS to css on the fly.
