* fix : remove cursor manipulation for input bindings Old Fix: Restore input binding selection position (#14649) Current Fix: Remove unnecessary cursor manipulation as the presence of runes no longer requires special handling. * fix : add change set to my previous commit * Revert "fix : add change set to my previous commit" This reverts commit 6ca8ef3. * fix: revert previous changeset added new to fix lint errors * chore : resolve lint error to fix pipeline issue * Revert "fix: revert previous changeset added new to fix lint errors" This reverts commit 9109494. * fix: input binding to handle code in a synchronous manner Introduced Promise.resolve to ensure that the 'set' operation completes before the 'get' operation Minimizing update delays. * Fix: resolve cursor jumps and change sets * better fix * test * changeset * simplify * failing test * gah we can't fix the input in an effect, need to do it here, but after a tick so that changes have been flushed through each blocks * add explanatory comment * fix test * this seems to work? --------- Co-authored-by: Hariharan Srinivasan <[email protected]> Co-authored-by: Rich Harris <[email protected]>

Closes #14630.
We can actually restore selection on an input that has
bind:valueand the input differs because of a function binding accessor. In fact, we can re-use the restoration logic implementation from React.Unfortunately, JSDOM doesn't seem to emulate selection changes when the value changes, so I didn't come up with a test.
