Language server issues in outline pane

Problem Description

Several “symptoms” involving the outline pane; I’m unsure how best to document, so looking for direction:

1. The outline often collapses. e.g. I expand all, then when working in the code it collapses.
2. The server busy spinner (next to the dropdown in the pane) randomly starts spinning. Sometimes this is accompanied by the editor and console hanging

What steps reproduce the problem?

1. Open a project
2. Work in some code

What is the expected output? What do you see instead?

Outline retains state (what is collapsed or not remains collapsed or not) UI does not hang with spinning server

eafpres 4.2.2 is out, FYI

As far as I can tell, the collapsing issue is solved (actually at least from 4.2.1). The spinning issue is there, but I need to attempt some kind of reproducible example in 4.2.2 If anything new / else appears, I’ll open a new issue. More to come, and as always, thanks.

[eafpres]

please test it once 4.2.2 is out.

Okay, will do. Thank you.
