When providing a list of completionItem with a non empty filterText, it seems that when typing only the 54 first characters of filterText are considered.

1. The first entry has filterText: RoWill2 Rogers, L. C. G. and William Diffusions, Markov processes, and martingales. Vol. 1 undefined. The o of Markov is in position 54 (counting from 0).
2. The second entry has filterText: RoWill3 Rogers, L. C. G. and Willia Diffusions, Markov processes, and martingales. Vol. 2 undefined. The o of Markov is in position 53 (counting from 0).

When typing o to narrow the completion to Marko, the first entry vanishes.

I apologise for not providing a reproducing example but I do not know how to simply provide a list of completions outside of an extension. I noticed this issue in LaTeX Workshop (I am a maintainer of it).
