Double pressing cursor routing button on "lnk" in browse mode doesn't activate it

[dkager]

Steps to reproduce:

1. In any browser, go into browse mode and position the cursor on a link.
2. Press the cursor routing button on a braille display above the control type label "lnk".
3. If the cursor wasn't on the first character of the link, it will now be moved there. In that case, repeat step 2.

Expected behavior:

The link is activated.

Actual behavior:

The cursor is routed if it is not already positioned at the start of the link, but the link is not activated when pressed again. The same for buttons and other controls.

System configuration:

NVDA version: master-14219,24cc3204
NVDA Installed or portable: Installed

Technical:

I suspect braille.TextInfoRegion.routeTo. The control type label can't be routed to but shares the same start position as the content following it.

To be clear: double routing anywhere in the link text does activate it. Routing once on the label "lnk" outside browse mode also activates it.
I would say P3 because this is very minor, but will become more relevant with #6802.
