Description:
I updated from LO 7.4 to 7.6, and there was a behavior change where certain .wmf files look worse than they did in 7.4.

Previously, importing .wmf files from a chemical structure editor drew all the lines with 0.01" thickness (and it looked good). Now, they're drawn with 0.00" thickness and I have to go in, break the object, select all the lines, and manually set them to 0.01". On top of that, when "breaking" the object, the components are scattered all over the page. I found that if the object is placed so that the top left corner is precisely at the top left corner of the page, things stay in place after breaking. The lines can then all be selected and set to 0.01", but this is unusably tedious especially for complicated drawings.

Regarding the line-thickness issue, I suspect it's from this commit: https://gerrit.libreoffice.org/c/core/+/146551

I linked to an example file and screenshot explaining what I mean in the 'Other Information' section.

Steps to Reproduce:
1. Insert -> Image -> .wmf file (I attached the one I used in the example)
2. Right click -> Break

Actual Results:
1. When the file is imported, all the lines are set to 0.00" thickness, which looks quite bad. They used to import as 0.01" thickness by default.

2. After 'Right click -> Break', the .wmf object's elements are randomly scattered all over the document. This doesn't happen if the .wmf is positioned exactly at the top-left corner of the page, however.

Expected Results:
1. Inserting a .wmf file should have the default line-width be 0.01", or perhaps have it possible to change the default

2. 'Right click -> Break'ing a .wmf object should keep all the components in place, as it used to do in LO7.4
