Corpus Viewer: focus in Line Edit

[ajdapretnar]

Expected behavior

Corpus Viewer uses Regex Filter in line edit normally (every typed letter is used as input consequently).

Focus in Regex Filter line edit shifts between canvas and Corpus Viewer, resulting in only odd (or even) letters being shown in the widget.

Corpus (bookexcerpts) - Corpus Viewer (use line edit).
