| While we're at it, if you're using Sentry in a Single Page App or meta framework, you might want to give the new `'page'` session lifecycle a try! | ||
| This new mode no longer creates a session per soft navigation but continues the initial session until the next hard page refresh. | ||
| Check out the [docs](TODO LINK) to learn more! |

This PR fixes multiple bugs and problems around browser sessions, mostly related to user id assignment:
When calling
Sentry.setUser()on static pages (i.e. no soft navigations), the user id would never be added to sessions. This is because in static pages, we don't send an"exited"session update. The fix: We send a session update whenever the user is set on the isolationScope (see comment about limitations)When calling
Sentry.setUser()in a single page application (i.e. with soft navigations), we would update the initial session with the user data when starting a new session for a new navigation. However, we did not include the user id on the new session, because thegetCurrentScope().getUser() || getIsolationScope().getUser()check was flawed. The fix: we use ourgetCombinedScopeDatahelper to get the "correct" (read, consistently like in other telemetry items) user.It seems like we had an incorrect check that would skip creating a new sessions for the first soft navigation after the pageload (in the default
'route') session lifecycle. The fix: We no longer check forfrombeing undefined.In addition, I also added a new
waitForSessionhelper and refactored most session integration tests to use this helper. This allows us to more granularly listen to multiple session envelopes simultaneously without running into collision risks.As a result of these fixes, session counts could increase as a whole but also metrics like "crash free users" will likely change. I added a note to the changelog calling this out.
Waiting on https://github.com/getsentry/sentry-docs/pull/16428/changes for final changelog note modification
