Duplicate clangd progress bar appears after running qmake

1. Open a large project, freshly cloned, not yet indexed by the clangd
2. Let clangd start parsing files
3. Change .pro files and rerun qmake on the main project

Second progress bar appears:

It disappears after a while, but it is a bit confusing, at first I thought it started two instances of clangd with both parsing same files.
