yq doesn't count the first line if it's a comment

[daydy16]

Describe the bug
yq doesnt count the first line if it's a comment. I want to get the line number of a specific value in a file. If the first line is a comment, yq doesnt count the line.

#test123 
abc: 123 
test123: 123123 
#comment 
lalilu: lalilu

yq e '.lalilu | line' test123.yml --> 4 (instead of 5)

If i change the first line to a regular value everthing works fine:

a: abc 
#firstcomment 
abc: 123 
test123: 123123 
#comment 
lalilu: lalilu

yq e '.lalilu | line' test123.yml --> 6

Version of yq: 4.27.5
Operating system: linux and windows (tested on both)
Installed via: binary release and choco

maybe related to: #1181

By default yq pre-processes header comments - this was a bit of a annoying workaround added to fix a number of issues with the underlying go-yaml parser :/

However, that workaround has some unwanted side effects, this being one of them. You can disable the header processing by adding the flag --header-preprocess=false - then you'll get what you expect.
