Description:
After opening certain DOCX files, the CPU usage of LibreOffice rises to 100%
even though the document has loaded already with all its visible content, and
the window has no user interaction.

The problem is still present in the 2018-11-17 build of 6.2.0.0.alpha1.

Steps to Reproduce:
1. Open the attached test.
2. Wait for it to load.
3. Observe CPU usage in top(1) or equivalent.

Actual Results:
CPU usage is 100%

Expected Results:
CPU usage should be negligible having loaded the document without user
interaction


Reproducible: Always


User Profile Reset: No
