view.sel() appears to not handle multiple views into a file correctly

[RobinWragg]

Description

view.sel() seems to always return the selections of the primary view into a file, even when called on a secondary view into the file.

Steps to reproduce

1. Install this plugin, which prints the current line to the console when a selection is modified:

import sublime
import sublime_plugin

class HighlightLongLine(sublime_plugin.ViewEventListener):
	def on_selection_modified(self):
		for region in self.view.sel():
			line = self.view.line(region.b)
			print(self.view.substr(line))

2. Open a file, then open another view into the same file, which I'll call View A and B.
3. Check the console output when moving the caret in each file.

Expected behavior

When browsing View A, the current line of View A will be printed to the console.
When browsing View B, the current line of View B will be printed to the console.

Actual behavior

When browsing View A, the current line of View A will be printed to the console twice.
When browsing View B, the current line of View A will be printed to the console twice.
It is not possible to obtain the selections from View B.

Environment

• Build: 3211
• Operating system and version: Windows 10

Thanks for your time.

Thanks for reporting. I believe this is a duplicate of #289

I see, it seems on_selection_modified() is being passed the wrong view.
