Issue description

If you have a RichTextLabel which uses BBCode and has a [bgcolor] tag, you cannot always see your text selection.

In particular, if the [bgcolor] spans over a line break, you cannot see your selection at all.

For example with this control:

If I highlight from before the end of the line the red text is not highlighted. (The additional red on the second like does get highlighted, though.)

Here is an example where the [bgcolor] is mid sentence and it works fine:

Steps to reproduce

I have included a MRP that demonstrates the issue. Simply start it and try to select text in the second line that goes beyond the wrap.
