fix(lsp): minimum height for floating popup #31990

Browse Source 
Problem:
The floating window for hover and signature help always cuts off a few lines,
because the `_make_floating_popup_size` function counts empty lines as having
zero height.

Solution:
Ensure the height is at least 1.

(cherry picked from commit a4f575abd8)
