Could we get away with a smaller delta here and leave most of the code intact so it's easy to revert? E.g.
// TODO(b/170675710): Stop unconditionally forcing legacy endpoint when fixed.
const forceLegacyEnpoint = true;
if (inColab || forceLegacyEndpoint) {
return this._requestDataGet(items, onLoad, onFinish);
} else {
return this._requestDataPost(items, onLoad, onFinish);
}That makes it obvious that we'll still need to the inColab check after resolving the TODO, which is better IMO than stating this fact in a comment. And I'm not sure we need to link to the spanner PR given that the gating factor isn't anything to do with the PR per se but rather with Google-internal release details which aren't particularly visible or meaningful outside Google anyway.

That's much more concise! Done.

The /scalars_multirun endpoint triggers errors when TensorBoard is
hosted with a Google Cloud Spanner backend. This change reverts
TensorBoard back to using
_requestDataGetunconditionally.Once [1] is synced into Google, we plan to re-enable the
_requestDataPostpath for non-Colab environments.Manually checked that the scalars dashboard makes GET requests
to
/data/plugin/scalars/scalarswith and without the?tensorboardColab=trueflag.Googlers, see b/170675710.
