<body>
This is the test for basic functionality of heap snapshot view grid.
<br>
<br>
To use this test:
<ul>
<li>load file in the browser;
<li>open DevTools (Ctrl+Shift+I on Win/Linux, Command+Option+I on Mac);
<li>go to 'Profiles' page;
<li>press 'Take heap snapshot' button
(eye icon on the left side of status bar);
</ul>
<br>
On the left pane under 'Heap snapshots' section, an item called
'Snapshot 1' must appear, and a grid with snapshot data must
appear on the right. Now test the following functionality in the grid:
<ul>
<li>change sorting order in each column by clicking on its header;
<li>resize each column;
<li>toggle between showing absolute times and percents
(button with percent sign on the status bar);
<li>double-click on numbers in 'Count' and
'Size' columns to toggle between times and percents for
this column only;
<li>expanding and collapsing tree nodes.
</ul>
