Completion doesn't show after some word preceded by *, (, [

Describe the bug For example the attribute completion only shows after insert [, but if i'm already inside square brackets the completion doesn't show or if i delete some characters and i want to trigger completion

To Reproduce Steps to reproduce the behavior:

1. Inserts [ goes to normal mode and returns to insert mode and try to trigger completion

Expected behavior Completion should appear even after [, (, * has been inserted.
