@dinhtungdu highlighted an issue within the Price Range filter of the Product Collection block, where the input handling for currency formatting is overly strict. The current logic clears the input if the space between the currency symbol and the numeric value is omitted (e.g., typing "20$" instead of "20 $"). This happens when in Curreny Options, currency position is "Right with space" as shown in screenshot below:

Steps to reproduce the issue

1. Add the 'Product Collection' block to a new post
2. Add "Price Range" filter in inspector controls
3. In Currency Options, set currency position to "Right with space" as shown in screenshot below:

4. Add any value to "Min" field of Price Range filter, for example 20. You will notice that it will have a space between value & currency symbol i.e. "20 $".
5. Now remove the space between value & currency symbol i.e. "20$". You will notice that after submitting this value, it clears the input field. Here is a quick demo video:
