Diagnostics Not Updated When Tree Not Visible

Hey,

I'd like a support for functionality where the diagnostics status and what not would be updated / reloaded upon NvimTree reveal? Is that currently possible? I did not see any configuration option that would enable such thing.

EDIT: There is nvim-tree.auto_reload_on_write that allows tree to update while being opened and a file is being written to. Also there is tree.reload() API that is tied to R command command and reload_on_bufenter configuration flag but non of these seem to give remedy to the situation. Like hitting R button does not seem to affect much to the state of the tree at least the diagnostics does not get updated. Same happens no matter I travel between different buffers. The only way for diagnostics to actually get updated seems to be by way of writing on buffer while keeping the NvimTree open.

Thanks for finding this one @juhaku

Diagnostic events are being received whilst the tree is closed however the nodes are not being updated:

[2023-11-07 10:32:58] [diagnostics] DiagnosticChanged
[2023-11-07 10:32:58] [diagnostics] DiagnosticChanged

Should see

[2023-11-07 10:33:40] [diagnostics] DiagnosticChanged
[2023-11-07 10:33:40] [profile] START diagnostics update
[2023-11-07 10:33:40] [diagnostics] update
...
