Triple click selection doesn't work

[Demetri0]

Describe the bug
It is convenient that triple-click (LMB) selects a paragraph, but in Foliate it is doing nothing (it seems like double click selects a word, and 3rd click deselect it)

To Reproduce
Steps to reproduce the behavior:

1. Open any e-book (fb2 in my case, but it should not be matter)
2. Hover on some word within paragraph of text
3. Use triple click of LBM (3 fast click in a row, like a double click but + one more ;))
4. See that paragraph haven't been selected

Expected behavior
Full text of paragraph should be selected.

Version:

• Foliate version: feba39e (gtk4 branch of Sep 1 2024)
• OS/Distribution and version: Ubuntu 23.10 mantic
• Desktop environment: GNOME 45.0
• Installation method: git #run-without-building-or-installing

Yes, it's quite unfortunate. The cause is, I think, that the selection popover is modal. Probably the selection popover should be made smaller, like only a single row. Then it can be more easily made non-modal. The popover would need to be non-modal, anyway, if one is to implement selection handles (#207).
