@Max0nyshchenko I already know of this issue.
But I haven't found a solution yet. :(
I'll notify you know when it's resolved.

@JiHong88 Thank you for your response, I was trying to fix it, but all in vain after 5hours of work. If I find time I'll get back to it.

@Max0nyshchenko I've just found the potential problem in core.js in the return line on function getSelectedElements:
lineNodes.slice(startIdx, endIdx + 1) gets the current element selected and the next one. However when you try to reselect the text, the builder doesn't recognize that that text was edited.

@matteocollina So I see you didnt push fixes? I didn't have time to work on it since
