This is the test for basic functionality of heap snapshot view grid.

To use this test:

• load file in the browser;
• open DevTools (Ctrl+Shift+I on Win/Linux, Command+Option+I on Mac);
• go to 'Profiles' page;
• press 'Take heap snapshot' button (eye icon on the left side of status bar);

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:

• change sorting order in each column by clicking on its header;
• resize each column;
• toggle between showing absolute times and percents (button with percent sign on the status bar);
• double-click on numbers in 'Count' and 'Size' columns to toggle between times and percents for this column only;
• expanding and collapsing tree nodes.
