Print Preview Does not behave properly when new "browser.tabs.insertAllAfterCurrent" setting is set to true

[stux2000]

As reported on IRC:

The following commit in PM unstable introduces a new feature "browser.tabs.insertAllAfterCurrent":

• https://github.com/MoonchildProductions/Pale-Moon/commit/e823327b33f6e8e4484952cd9e9ab1fd00a4e8c3

If this feature is enabled and the "Print Preview" feature is used, after closing the preview a different tab from what was previewed is shown. This may be caused by clashes in how PM and TU handle tab creation.

Also during testing on current PM stable (28.10.0) when using the tabs on Left or Right feature, the print preview keeps showing the tabs and also returns to a different tab.

After reviewing the issues I suspect that issue #7 is part of the cause of this issue.

comment from IRC:
Tab Mix Plus has a special setting for closing a tab, focus: Opener/right tab
with that instead of just Right Tab print preview reverts to the opener, in that case the printed site

It seems that the above setting could work around the issue. The "Tab Closing" settings may provide an appropriate workaround as well.
