Steps to reproduce

1. Launch Firefox.
2. Access the following link
3. Select a portion of text. Ex: “into position on the raised “.
4. Hit CTRL + P.
5. Select “Selection” from the Page Range options.
6. Print the file.

Expected result

• Only the desired selection is successfully printed.

Actual result

• The print job returns a blank page or if trying to select the “As she does so, a fine mist of tiny water droplets burst forth from her airways, the bright lights off to one side making their swirling movements visible” portion, it only prints the ending part (“movements visible”).

Regression Range

• This doesn’t seem to be a regression since this is reproducible with older builds as well (goes way back to 2017).

Notes

• Please observe the attached screencast for further information regarding this issue.
• This issue doesn't seem reproducible on Chrome
• [Suggested Severity] I'm not sure if this issue will be encountered on other webpages that are frequently printed. But the outcome here is that the user can't print the desired selection and I didn't find any easy/reliable workaround. I think that making this an S2 or S3 issue fits here.

This problem appears to be fixed for the most part now. However, the first letter of the selection is missing sometimes. (Nightly 20201109095222 on Linux)
