costumes.test failed on travis, but not locally (integration) #5014
Description
costumes.test failed several times yesterday on the line https://github.com/LLK/scratch-gui/blob/f2ac39fe0e0faa70d1003d7efdb096cd2eb268ec/test/integration/costumes.test.js#L100
It would timeout looking for //body//*[@id='react-tabs-3']//*[contains(text(), 'Convert to Vector')]
On rerunning the PR build today it passed. It may have just been a transient failure due to the package-lock changes this week, but opening this issue so that we know if it reappears.
