fseditor.js crashes when PgDn key hit... sometimes

I hadn't seen one of these crashes in a while, but it happened just now:

The impossible happened: (line[l]) = {"text":"","attr":"","hardcr":false,"kludge
d":true,"firstchar":0,"selected":false}
line[l+1] = {"text":"","attr":"","hardcr":true,"kludged":false,"firstchar":0,"se
lected":false}
l 29   

added bug label

mentioned in issue #243 (closed)

This crash occurred again today, when hitting PgDn:

The impossible happened: (line[l]) = {"text":"","attr":"","hardcr":false,"kludge
d":true,"firstchar":0,"selected":false}
line[l+1] = {"text":"","attr":"","hardcr":true,"kludged":false,"firstchar":0,"selected":false}
l 11  

Just happened again:

The impossible happened: (line[l]) = {"text":"","attr":"","hardcr":false,"kludge
d":true,"firstchar":0,"selected":false}
line[l+1] = {"text":"Try setting the BaudRate in your sexpots.ini file or passin
g the -baud ","attr":"\u0007\u0007\u0007\u0007\u0007\u0007\u0007\u0007\u0007\u00

,"firstchar":0,"selected":false}
l 20       

This time I'm pretty sure I just hit down arrow key:

The impossible happened: (line[l]) = {"text":"","attr":"","hardcr":false,"kludge
d":true,"firstchar":0,"selected":false}
line[l+1] = {"text":" > ","attr":"\u0007\u0007\u0007","hardcr":true,"kludged":fa
lse,"firstchar":0,"selected":true}
l 13   

Another occurrence:

The impossible happened: (line[l]) = {"text":"","attr":"","hardcr":false,"kludge
d":true,"firstchar":0,"selected":false}
line[l+1] = {"text":"","attr":"","hardcr":true,"kludged":false,"firstchar":0,"selected":false}
l 14            

This or similar is still possible:

I guess this could be arguably politics/debate, but I just wanted to mention
*somewhere* that I deactivated my Twitter/X account (@digitlman) last night. No
big loss. I would occassionally post new YT video notices or software release
announcements there, but that's about it.

I just couldn't stand the thought that my account was somehow adding to the
numbers that supported Elon Musk and own private BBS/platform. Fuck that guy.
