vim / neovim - autocomplete stop working after seven repetitions

[ardaij]

I use vim / nvim as editor. The code to completion working.
But if something happens seven times in a program, this stopped working.

For example:

import cadquery as cq
part = (cq.Workplane("XY")
.circle(10)
.extrude(10)
.faces(">Z")
.circle(10)
.extrude(10)
.faces(">Z")
.circle(10)
.extrude(10)
.faces(">Z")
.circle(10)
.extrude(10)
.faces(">Z")
.circle(10)
.extrude(10)
.faces(">Z")
.circle(10)
.extrude(10)
.faces(">Z")
.circle(10)
)

After the seventh ".circle()", (or seventh .lineTo(), etc. ) the code completion stop working.
I tried this with several add-ons, always the same result.

"davidhalter/jedi-vim", "ncm2/ncm2-jedi"

I thought this was a cadquery bug, I reported this problem on the cadquery (CadQuery/cadquery#823).
I received this answer:

"This is not a CadQuery problem. You probably should report this to vim/nvim developers or to developers of whatever auto-completion plugin you are using with it."

Could this be a vim / neovim or ncm2-Jedi question?
