Looks like the DiagnoseParser is doing a lot work. After it's done, the proposal renders correct but it takes 5s to compute all labels for LoggingAdapter:

I will take a look at for 4.6. Unlikely for 4.5.

Comment 2 Jay Arthanareeswaran

2016-04-05 04:34:14 EDT

No progress yet and unlikely to get time during 4.6. Moving out.

Comment 3 Manoj N Palat

2018-05-21 06:07:02 EDT

Bulk move out of 4.8

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
