Bash Version: 4.4 
Patch Level: 12 
Release Status: release 

Description: 
Bug happens in an interactive shell. 

this works as expected, no history expansion : 
echo "foo"'!bar'"qux" 

but this fails, bash tries to hist-expand !bar', which it should not. 
echo "foo 
"'!bar'"qux" 

-bash: !bar': event not found 

I just compiled bash 4.4.18 and tested, the bug is there too.
