STEPS TO REPRODUCE THE PROBLEM:
Enter a search term in Google. Select it (in order to correct it, replace it,
delete it, etc.) by dragging with the stylus from the end of the entry to the
left of the beginning of the text entry field.
EXPECTED OUTCOME:
The text should be selected and the keyboard should be visible in order to make
changes.

ACTUAL OUTCOME:
The text is selected but keyboard does not appear unless the users tap into the
field again and consequently deselect the selected text. 

REPRODUCIBILITY:
Always.

OTHER COMMENTS:
The problem does depend on dragging just beyond the left border of the input
field. If the user is very careful, they can highlight the entire field without
having the VKB disappearing but it requires quite a bit of manual dexterity.
Presumably the VKB disappearing is intentional since you don't want it around
when you select parts of webpages that have no data entry capability.
Unfortunately, it has an annoying consequence when part of that selected area
is an input field.
