Taskboard test fails on "Add in place" a card. The failure depends on the network:

If the network is slow (or the CPU is slow, as can happen on a CI machine), the test will select the "Add in place" button. Before it can click it, the other children of the swimlane will load and render. Vue will update the DOM, which will leave the previous "Add in place" button dangling (not connected to the DOM). Cypress will then complain because it's unexpected.

The test should wait for the swimlane and its children to be loaded before attempting to add a new card.
