DESCRIPTION

In some PDFs, text selection is nearly impossible. I have attached an example
of a schematic diagram created with KiCad. The video demonstrates the problem.

When trying to select text, other areas of the PDF are selected as well. As a
result, it is extremely difficult to select and copy the desired text to the
clipboard.

STEPS TO REPRODUCE
1. Load <<BHBM_V7.pdf>>
2. Review the video:

3. Try same as shown in the video

OBSERVED RESULT

When trying to select text, other areas of the PDF are selected as well.

EXPECTED RESULT

Only text should be selected and marked.
