[BUG] Code formatting mess upon inserting new parenthesis

If there is a line of code like this:

page.10.file.stdWrap.wrap { [...]

which, at a later point in development, shall be changed to this (by inserting parenthesis between "10" and "file"):

page.10 { file.stdWrap [...]

a newly formatted result similar to the following excerpt is generated:

page.10{ . }file[...]

Please also look at the attached image.

This does not happen in, e.g., CSS, where similar scenarios evolve, therefor I assume it is an error that should be reported here: Please correct me, if I am wrong.

Thank you!

Best regards! Robert
