Key/option autocompletion exits after typing in a space

[muzimuzhi]

Environment

• TeXstudio: 4.7.0beta1
• Qt: 6.6.0
• OS: macOS 13.4.1
• TeX distribution: irrelevant

Expected behavior

When typing in a key containing space(s), hit space continues autocompletion.

Actual behavior

The autocompletion exits immediately after typing in a space.

How to reproduce

To use tikz option line width=1pt, type in "line" and the autocompletion pops and reduces normally, then hit space. The autocompletion exits.

(maybe as a workaround) enter space as ctrl+space

This workaround shows a further problem: when you then type w then the completer positions on line width=. But now pressing ctrl+space inserts white.

Fix is ok from my side, thanks.
