Nope, that is deliberate.  Use ^U to delete the text, if that is what you
want: Esc was never documented to do so.  The problem here is that some
other process (for example a GUI widget) might have written something to
the screen, and you don't want that deleted.

Moral: don't rely on undocumented side effects.

The critical thing here is that you are using winhelp, and that is
`rough'.  It works with all the four other help systems.  Can we persuade
you to move into the 21st century and used winhelp's replacement, CHTML?

Argh. Looks like Jitterbug is having trouble if the Subject line
becomes longer than 80 characters. Looks like I'll need to go fix
bugs in the bug tracking software again! Meanwhile, could you please
truncate the header on followups on PR#799?

This is getting tiring. Anyone have suggestions for an alternate
bugfiling device that is actually being maintained, is easy to handle,
integrates well with the mailing lists, and doesn't require weird
sysadminning tasks such as adding one new mail user per bug report?
Bugzilla maybe?
