Search not searching all dropped files

[vscodenpa]

Type: Bug

To reproduce:
Drag and drop multiple files (for the purpose of reproducing, do not navigate between them).
Open search [CTRL][SHIFT][F]
Enter a search term.

Actual result:
"X results in 1 file."
Search results are only returned for files that have been given focus. To obtain results from the other files they must be given focus first and the search repeated.

Expected result:
All matches should be returned for all opened files.
