Adding a space after periods messes with (text:1.1) syntax

[Hapseleg]

adding a space after period messes with weighting syntax (mouse:1.1) turns into (mouse:1. 1) which invalidates it

I agree, cleaning the existing text can break the entire prompt. I hope this gets merged :)
If the original issue was to be sure to have a comma separating to new tags from the existing tags, maybe a fix can be:

Suggested change

	return existing + newText;
	return existing.split(",").concat(newText.split(",")).join(",");

Thanks for submitting these, I've been working hard on the lora sidebar trying to get it into a good place and I'm almost there, I'll try to give these changes a review here in a day or two and merge things up!
