Coc inline diagnostics stop working when I open coc-eplorer

[shadowphoenixpt]

Describe the bug

Hello all,

I have been experimenting with coc-explorer to replace NERDTree. It mostly works fine, but I've stumbled upon a problem. After I open coc-explorer, I no longer get coc's inline diagnostics. I have experimented with both echo and float inline diagnostics, but it doesn't work on both. I have also tried different terminal emulators to no avail. The problem persists even after I close coc-explorer. I need to restart vim to bring diagnostics back.

Thank you.

Steps to reproduce

To see inline diagnostics

Having the same problem. Just opening the file with vim works as expected. But once opened with coc-explorer, it no longer shows any diagnostics. The signs are shown though, but not the messages.

I just updated CoC and all plugins and am now experiencing this. Error floats work as expected until sometime after coc-explorer is opened, sometimes immediately, sometimes it will show a couple more before they stop working. Rolling back CoC to the last release commit, 1d3c525, tagged v0.0.82 gets everything working again: https://github.com/neoclide/coc.nvim/releases/tag/v0.0.82

Update: Also finding that I need to rollback a couple other plugins like coc-tsserver to versions released around the same time, which makes sense, but thought it was worth mentioning.
