Fix selection after running a settings quick action #2756
Created by: b-j-p
Fixes https://github.com/sourcegraph/sourcegraph/issues/2756
Assumption: there are some quick configure actions for which a selectText
may be set a priori, and then there are other quick configure actions for which this is not possible.
The change that I am proposing offers a handy way to generate selectText
a posteriori, taking the whole editor into consideration, after all changes have been applied.
