Helix becomes very slow when the file contains ultra long lines

[ysooqe]

Summary

Helix becomes unusuably slow when a file contains at least one super long line (millions of characters on that line).
I noticed this since I wanted to look through an XML file that had some serialized JPGs in it (where one serialized JPG resulted in a line length of about 8M characters).
I have uploaded a simple TXT file ( test.txt ) where the exact same thing happens.

I have looked through the other issues and found #338 as well as #3072 , but I am not entirely sure if this is related. The example-file I uploaded is only 7MB, but it already forces Helix to its knees.

Reproduction Steps

1. Open the uploaded file with helix
2. Try to move around (e.g. with hjkl)
