            Bug ID: 212201
           Summary: [css-grid] WPT test
                    css/css-grid/grid-definition/grid-limits-001.html is
                    very slow and uses too much RAM
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

The WPT test css/css-grid/grid-definition/grid-limits-001.html is very slow when executed in WebKit and uses too much RAM.

Sometimes it even crashes for me with this loud error coming from the WebProcess:

"Unable to shrink memory footprint of process (9248 MB) below the kill thresold (4096 MB). Killed"


The issue its both reproducible, either by running our imported layout test imported/w3c/web-platform-tests/css/css-grid/grid-definition/grid-limits-001.html (I'm importing it on bug 212187) or by running the upstream wpt test from https://wpt.live/css/css-grid/grid-definition/grid-limits-001.html

You can see how the tests takes a while to execute (like 10-20 seconds) and the memory usage peaks around 9GB !

This issue its not reproducible with chrome or firefox:

 - with Chrome the test executes quickly, uses few RAM (~250M) but it fails the tests
 - with Firefox the test executes quickly, uses few RAM (~400M) and it passes ok.
