My two cents here:

What you've run into is something that is *very* hard to uncover in 
automated tests, of which there are quite a few and more added all the 
time. I've added several to the test suite myself. But working with 
something like the script editor really requires an interactive manual 
mode to uncover discrepancies. It's not so much that you have found an 
edge case, it's more that changes to code in the engine or IDE stacks 
can have some unintended side effects for which there are no existing 
test cases.

I think it's unfortunate that the team is reluctant to refer to the dp 
releases as beta builds, because that's what they are. The alpha testing 
is done at every build/check-in of code, and then at some point the 
decision is made to release a new beta version for a wider target for 
testing. Your finding the script editor problem with long scripts will 
result in a fix that will help everyone who has to struggle with editing 
scripts on Windows.

As a side note, the main stack script of the glx2 script editor is now 
about 8500 lines of code, and it was previously about twice that, and 
had similar problems with long scripts. In the process of refactoring 
with an eye towards DRY and single-responsiblity code it got more 
responsive. But this was nothing I could test automatically - more of a 
recursive process of "tweak this, see what effect it has".

I feel your pain in regard to dp releases - dp6 is the last LC9 release 
that is usable for me for a number of reasons, and the binary-level 
incompability of extensions makes switching between LC8 and LC9 awkward.

LOL. Understood.
