Dashboard logs "jump to end" button does not seek to end on first effect

[tscurtu]

Reproduction: Launch a pipeline with a Run that is supposed to print more than one page in the logs. Click to the Run's Logs panel, and click the "jump to end" button until logs appear.

Effect: The logs are loaded, with a scroll bar, but the pagination does not seek to the end of the logs stream, as the button name suggests. Subsequent clicks of the button will indeed seek to the end of the logs stream.

Expectation: The logs view should always seek to the end of the logs stream when clicking "jump to end". "load next" covers the case where we don't want the rendering to seek to the end.
