'I searched for "version" ...'

On the basis that version notes often look like "introduced in 5.nn", I searched for "34": 8 instances found; none relate to this issue.

'... but shows ... shouldn't it rather be "ignores" or "tolerates" whitespace?'

I believe that was intended to contrast with the previous line (\x{263A} vs. \x{ 263A }). Depending on device, browser and font, the difference between \x{263A} and \x{ 263A } may not be all that obvious.

Regardless, a ninth note (e.g. [9] Introduced in v5.34.0.) would add clarity.
