Spacebar not working while code is being inspected

Rubberduck version information

Version 2.5.1.5557
OS: Microsoft Windows NT 10.0.18363.0, x64
Host Product: Microsoft Office x86
Host Version: 16.0.12527.21330
Host Executable: EXCEL.EXE

Description
While Rubberduck is inspecting the VBA Project, any spaces entered into the VBA Code window on the end of an existing line of code get removed instantly.

To Reproduce
Steps to reproduce the behavior:

1. Open a project with a large enough codebase so Rubberduck's inspection process takes long enough to see the issue.
2. In a module or class, try pressing the spacebar to enter a space at the end of an existing line of code.
3. You should see that the space character appears momentarily before being deleted.

Expected behavior
That space characters can be entered while Rubberduck is inspecting the code.

Exactly none of the inspections interact with the code panes, but the VBE itself will suppress trailing whitespace on a line of code.

Are autocompletion features enabled? That's a more likely lead than inspections.
