Hi, I know tinymce does source code sanitization and modification by design. But I have a case that I don't want to make it happen (I think there are other people that want this too). In my project, I am using tinymce to create templates that use handlebar tags. For example:

when I put <img src="data:image/jpeg;base64,{{SOME_SRC}}" /> this img tag with this source (this SOME_SRC will be populated later, this is handle bar tag) and in first tinymce's modification it becomes this <img src="data:;base64,{{SOME_SRC}}" /> this. And If I refresh the page saving this template, it just becomes <img />. The src is removed, I guess this sanitization that is being made in editor's initialization is different.
I don't want it to happen. I got around other cases even with this sanitization, now this is the only problem for me.
I want to solve this problem, and If it is possible, can there be any way stop this source code modification altogether

Thank you
